Scoring a hole-in-one is the greatest shot a golfer can make. Once 4 professional golfers each made holes-in-one on the 5th hole at the same golf course at the same tournament. It has been found that the estimated probability of making a hole-in-one is 12905for male professionals. Suppose that a sample of 4 professional male golfers is randomly selected.
(a) What is the probability that at least one of these golfers makes a hole-in-one on the 13th hole at the same tournament?
answer:
(b) What is the probability that none of these golfers make a hole-in-one on the 13th hole at the same tournament?

12905?

anonymous · Answer

conditional probability.. too lazy to solve it

anonymous · Answer

apply bayes' theorem

inkyvoyd · Answer

If the probability of making a whole is higher than one, I do believe that you have some serious golfers.

It has been found that the estimated probability of making a hole-in-one is 12905.
Probability values lie between the closed interval [0,1]. 
There's a decimal or something missing here: making a hole-in-one is 12905.
Please correct. Thanks.
