Fifty-six percent of all american workers have a workplace retirement plan. if americans retirement plans are independent, what is the probability that exactly 3 out of 5 randomly selected americans will have a retirement plan

We have been given that 56 percent of all American workers have a workplace retirement plan and we are also given that  Americans retirement plans at workplace are independent.

To find out  probability of exactly 3 out of 5 randomly selected Americans will have a retirement plan we will use Bernoulli trials.

where p is probability of a success which in this case is Americans that have workplace retirement plans  and q is probability of failure which in this case are Americans that don't have workplace retirement plans.

Upon substituting our given values in this formula we will get,

Rounding our answer to nearest hundredth we get our probability that exactly 3 out of 5 randomly selected Americans will have a retirement plan is 0.34.

if x = 1, then the answer is 3.5
