Examples : 4 - Probability (Part - 9), Math, Class 10 Video Lecture

hello friends this video in probably
part night is brought you by exactly a
calm no more fear from exam before
watching this video please make sure
that you have washed part part 2 part 8
again consists of tossing one rupee coin
three times and then nothing easy over
hundred pence if all the tosses get the
same result that is three heads or three
tails and loses otherwise find the
probability that he lose them so we have
head and tail of them and this is Stosh
3000 so so let's suppose in the first
time you got a let me draw here okay and
this is the foster now the second time
also you may get head and pin here also
you may get hit in pain third time was -
you may get hit you may need to take
mainly hit make it leave it also you may
get head and you may get it right first
time you may get head and tail first
this first second time again it's not a
normal this is the flow we have first
time head head then hit-the hit-the
hit-the hit-the hit
so this guy wins only if he ate three
conservative head that is this possible
chain or three concede it in the
distance so if I jot down all the
possible values what I get is ebayid
head head head this is the first chain
or he make a head head tail the second
chain or this is my gate head tail head
heart chain or head tail tail for chain
fall from tail tail head head or tail
head tail tail head tail or tail tail
head tail head or tail Dilton
so they are 1 2 3 4 5 6 7 8 outcomes and
out of this only in case of these two he
will will correct so prepare tea or when
is nothing burned say even if element
right nothing going out for my not long
term so what is the thing I will out
them and time on when say when in two
scenarios and total scenario are eight
at this one where so probability of
winning is 1 by 4 the question says
probably of losing so probability of
loss is nothing but 1 minus rapidity of
in current because probability of loss
is nothing but prevent do win - this
becomes 1 minus 1 where oh that is so
Rivera T of honey losing the game is
free by flow right very simple just
understand this if you understand this
tree structure the problem is simple you
got this set that the protein number of
outcome is these Rather's out of this
these two are the nobility of winning
others are quality of a die is shown
twice
what is it provided that five will not
come either type and five will come at
least when he throw or dry first time
you'll get one two three four five six
any of this and second time also will
get same number
she is want to find total set there are
36 elements actually get 6 into 6 6 into
36 outcomes so that is total outcome is
nothing but outcome learning about 36
hours question is asking 5 will come up
either time fire will come in at least
one name so let's find all this right
all the outcomes where you get fine so
let's suppose 5 is the first time only
so you get five one five two five three
five four five five five six all
possible is we have I came in the first
second is verify scheme the second time
so with one you get five in two you got
5 with three you got five four you got
five you five it works
61 5 this is commerce I can cancel this
because this is already covered yet so
they are actually one two three four
five plus six 11 possible outcome where
you have five okay the question says
five come either time means at least it
should come I should come at least one
thing if I should not come in shortly so
first you'll find five should come one
time and then find a compliment so five
come one time they love the same thing
see wherever I would combine go till out
them what is the favorable outcome five
comes at least one times the eleven out
pump we can see we have five came at
least one one of wood and total is 36
feedom so this is the outcome pot five
came at least one times the question
says five does not come at this one time
so that means fine come one time
complement this is what the question is
asking for this becomes 1 minus five
come one time there is one minus learn
by 36 and that comes out to be 25 by 36
of the probality off fine not coming
either
then if the second question say is that
5 will come at least once this is what
we have solved all right 5 come at least
one that is 5km one or more times there
is 11 here and total outcome is that
this is the lamp is advancing so let me
write here once again fine come at least
once is nothing but favorable all
combined don't you longer participate
bail out them 11 5 comma - what's 11 and
please note here this this is 50 part
here if I
are twice so ignore it don't buy the
toys as you get different answers so
only thing is we go down all the values
all the possible at home here we had to
