Important Questions: Probability - Question 2

Which of the following cannot be the probability of an event?

Detailed Solution for Important Questions: Probability - Question 2

∵ Probability of any event cannot be more than 1.
∴ 1.5 can not be the probability of any event.
∴ (a) is the answer.

Important Questions: Probability - Question 3

An event is very unlikely to happen. Its probability is closest to

Important Questions: Probability - Question 4

A coin is tossed twice. The probability of getting both heads is

Detailed Solution for Important Questions: Probability - Question 4

Sample space - {HH, HT, TH, TT}
Number of total possible outcomes = 4
Number of favourable outcome (both heads) = 1
∴  Probability of getting both head = 1/4

Important Questions: Probability - Question 5

The probability expressed as a percentage of a particular occurrence can never be

Important Questions: Probability - Question 6

The probability that a non leap year selected at random will contain 53 Sunday's is

Detailed Solution for Important Questions: Probability - Question 6

A non-leap year has 365 days

A year has 52 weeks. Hence there will be 52 Sundays for sure.

52 weeks = 52 x 7 = 364 days .

365– 364 = 1 day extra.

In a non-leap year there will be 52 Sundays and 1day will be left.

This 1 day can be Sunday, Monday, Tuesday, Wednesday, Thursday, friday, Saturday, Sunday.

Of these total 7 outcomes, the favourable outcomes are 1.

Hence the probability of getting 53 sundays = 1/7.

Important Questions: Probability - Question 7

A fair dice is rolled. Probability of getting a number x such that 1 < x < 6, is

Detailed Solution for Important Questions: Probability - Question 7

1, ∵ It is a sure event.

Important Questions: Probability - Question 8

A die is thrown once, the probability of getting a prime number is

Important Questions: Probability - Question 9

The sum of the probabilities of all elementary events of an experiment is p, then

Important Questions: Probability - Question 10

The probability that a number selected at random from the numbers 1, 2, 3 ... 15 is a multiple of 4 is

Detailed Solution for Important Questions: Probability - Question 10

The numbers that is a multiple of 4 present between 1-15 are 4,8,12.
total numbers between 1 to 15=15,
the probability of getting a number that is a multiple of 4= number of favourable outcomes of event e/ total number of outcomes.
=3/15
=1/5
