Answer:
0.549 or 54.9%
Step-by-step explanation:
This is a binomial distribution (Bernoulli's experiment), where the probability of “success” (selecting a battery with acceptable voltage) is 0.9 and the probability of “failure” is 0.1
So, the probability of selecting at least 14 acceptable batteries out of 15 is
where <em>C(n, m) are combinations of n elements taken m at a time</em>.
C(15,14) = 15
C(15,15) = 1
so, the probability we are looking for is
