Brown Eyes Find the probability that among six randomly selected people, exactly four of them have brown eyes.
ANSWER:Problem 2RE
Answer:
Step1 of 1:
We have In Exercises, assume that 40% of the population has brown eyes (based on data from Dr. P. Sorita at Indiana University) that is p = 40% = 0.40.we need to find the probability that among six randomly selected people, exactly four of them have brown eyes.
Here,
P = 0.40 n = 6
Consider a random variable “x” follows binomial distribution with sample size “n” and proportion “p”.
