Q:

99 POINTS WILL GIVE BRAINLIEST!! No fake answers!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 three programs she examines?A) 0.15B) 0.27C) 0.59d) 0.73A fair coin is flipped multiples times until it lands on heads. If the probability of landing on heads is 50%, what is the probability of first landing on heads on the fourth attempts?A) 0.625B) 0.0625C) 0.500D) 0.382

Accepted Solution

A:
1. Chance of finding a bug = 0.35Chance of not finding a bug = 1 - 0.35 = 0.65Probability of finding a bug in the first 3 programs = Probability of not finding a bug in 2 out of the 3 and finding a bug in 1.:0.65^2 * 0.35 = 0.147 = 0.15Answer is A.2.Probability of heads = 0.50Probability of tails = 0.50Probability of heads on the fourth attempt = tails x tails x tails x heads = 0.5 x 0.5 x 0.5 x 0.5 = 0.0625The answer is B.
