2. Assume a cardiovascular surgeon has implanted 13 pacemakers in his patients from a new batch of pacemakers that have been found to have a defect that causes them to stop working. If each pacemaker has a 23.47% chance that it will work, what is the probability that all the patients’ pacemakers will work the way they are supposed to?

A) 6.556e-9

B) .0527

C) .4730

D) .5270

Step 1

**Binomial distribution:**

The binomial distribution gives the probability of number of successes out of *n* trials in a series of Bernoulli trials. The probability mass function (pmf) of a binomial random variable *X* is given as:

Step 2

**Calculation:**

It is given that 13 pacemakers are implemented for the patients and each pacemaker has a 23.47% probability that it will work. The random variable *X *denotes that the number of pacemakers t...
