Question

In each of the following cases, name the distribution that can best be used to describe the random variable X and give the value of all necessary parameters for that distribution:

1. i) You have a bag of 100 M&M’s. 30 are green. If you grab a handful of 10 M&M’s, let X be the number of green M&M’s you grab.

2. ii) Next you ask your neighbor if they like M&M’s. Assume that 70% of all people like M&M’s. Let X = 1 if they say yes and X = 0 if they say no.

Answer 1

Answer: w this is byper geometric distribution with parameter n. N- Total population size= 100. Sample size in=10 . Success element a number of green M&m's K-30. ii) this is Bernoulli distribution with parameterp P-probability of liking M&M = 0.7 Thank you
