Question

there are 4 boys taking turns shooting basketballs. Each boy has a 10% chance of making a basket. What are the odds all 4 boys make the shot, in a row?

Answer 1

The probability that a boy will make a shot = 10/100 = 0.1

Here the probability of one boy making a shot is independent of another

==> Probability of all 4 boys make the shot = 0.1*0.1*0.1*0.1 = 0.0001

The odds of an event is the ratio of the number of outcomes favorable to the event to the number of outcomes unfavorable to the event. It can also be calculated by

Odds = p/(1-p) where p is the probability of the event

Here p = 0.0001

Odds = 0.0001/0.9999 =

Therefore the odds that all 4 boys make the shot in a row =
