Question

there are 28 students in a college cricket team .what is the probability that at least 3 of them have their birthday in the same month?

Answer 1

Use formula

events/number of outcomes

events- represents the situation in which the probability needs to be determined.

number of outcomes- the total of the given situation

In this situation, 3 students sharing the same birthday is the event and the total number of students is the outcome.

Plug in

3/28

3 represents the event

28 represents the total outcome

3/28 = .10714 * 100 = 10.714

10.7 -> 11

Answer

There is an 11 percent chance that at least 3 of the students will have their birthday in the same month.
