D.
37%

Answer 1

Answer: The correct answer is D) 37%

Explanation:

We can use our binomial model equation with all the relevant information to solve this problem simply. We just need to dissect the problem a bit to find relevant information. We know that out of 16 batteries in a pack (the number of trials in this case) we want to find the possibility of 1 of them (the number of successes) to be defective with a defective rate of 5% or 0.05. We simply input the data into our binomial formula given and solve for our answer of 37% I hope this answer has been of use.

Have a wonderful rest of your day :D
