Suppose that it is known that 10 percent of a certain population is color blind. If a random sample of 20 people is drawn from this population, answer the following:

1. What is the probability of five or fewer are color blind and what is the probability that 6 or more will be color blind?
2. What is the probability between 6 and 9, inclusive will be color blind? Additionally, What is the probability that two, three or four will be color blind?

Expert Solution

Step 1

P(color blind)=0.1

n=20

Let X be the no. of color blind

$X ~ B i n o m i a l (20, 0.1)$
