Acomputer programmer has a 35 chance of finding a bug in any given program. what is the probability that she finds a bug within the first 3 programs she examines?
a) 0.15
b) 0.27
c) 0.59
d) 0.73

Answer is d

Step-by-step explanation:

A computer programmer  has a 35 change of finding a bug in any given program.we have to find probability that she finds a bug within the first 3 programs she examinessuccess = 0.35, failure = 0.65She get a bug in the first program itselfp = 0.35She get a bug in 2nd program q = 0.65×0.35 =0.2275She get a bug in the 3rd programr = 0.65×0.65×0.35 r = 0.147875Add all the three probabilities for answerP = p+q+rP = 0.35+0.2275+0.147875P = 0.725375P = 0.73The probability of the answer is 0.73
