A sharpshooter can hit the target with a probability p=0.75.

a) What is the probability that out of 10 shots she misses them all?

b) Find the probability that out of 10 shots she gets the target at least once.

Success:  p = 0.75

Fail:  q = 1 - p  = 0.25

 

a)  Prob of missing all 10 shots = q10 ≈ 9.5*10-7

 

b) Prob of at least one success = 1 - prob of no successes = 1 - q10.
