Two fair coins are tossed simultaneously. Find the probability ofGetti...
When two coins are tossed, the sample space of possible outcomes would be the set
S = {HH, HT, TH, TT}
where H: the outcome is a “Head” and T: the outcome is a “Tail” and the probabilities associated with each of these outcomes are equal assuming the coins are fair.
When we say at most 1 “Head” outcome, it means that only 1 of the two coins show up a head or that the no “Head” outcome shows up.
If A is the event obtaining only 1 “Head” outcome, then the set of outcomes that makes up event A is
A = {(HT), (TH)}
Hence, the probability of event A is
P(A) = 2/4

Number of head in a coin=1
number of tail in a coin=1
Total number of faces of a coin=2
probability (getting a head) =number of favourable outcome/Total number of outcome
=1/2
Hence, A is correct
number of tail in a coin=1
Total number of faces of a coin=2
probability (getting a head) =number of favourable outcome/Total number of outcome
=1/2
Hence, A is correct

Ans Total number of outcome=4 (HH,TT,HT,TH)
Favourable outcome=2 (HT,TH)
P(getting only one head)=No of favorable outcome/Total no of outcome=2/4=1/2
So, the ans will be 1/2
option (a)1/2 is correct
Favourable outcome=2 (HT,TH)
P(getting only one head)=No of favorable outcome/Total no of outcome=2/4=1/2
So, the ans will be 1/2
option (a)1/2 is correct
