A computer 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 examines success = 0.35, failure = 0.65 She get a bug in the first program itself p = 0.35 She get a bug in 2nd program q = 0.65*0.35 = 0.2275 She get a bug in the 3rd program r = 0.65*0.65*0.35 r = 0.147875 Add all the three probabilities for answer P = p+q+r P = 0.35+0.2275+0.147875 P = 0.725375 P = 0.73 The probability of the answer is 0.73
