Answer:
The probability that 4 adults selected at random from the town all have health insurance is 0.1897
Step-by-step explanation:
Consider the provided information.
It is given that 66% of adults have health insurance.
Let p = 66% = 0.66
Therefore q=1-0.66=0.34
We need to find the probability that 4 adults selected at random from the town all have health insurance.
Here the value of r is 4.
Substitute the respective values in the above formula.
Hence, the probability that 4 adults selected at random from the town all have health insurance is 0.1897
