can someone do question 9-13 please?

Consider the random variable which has the following probability mass function: x_x(x) = 1/30 x^2, x = 1, 2, 3, 4 Compute P (X lessthanorequalto 2) (Report answer to three decimal places. Answer must be within +/0.001 of correct value) Consider the random variable X, which has the following probability mass function f_x(x) = 1/30 x^2, x = 1, 2, 3, 4 Compute P(2 lessthanorequalto X lessthanorequalto 3) (Report answer to three decimal places. Answer must be within +/0.001 of correct value.) Consider the random variable X, which has the following cumulative distribution function: F_x(x) = { 0 x

Explanation / Answer

Answers

Question 9

P (X 2) = P (X = 1) + P (X = 2)

               = 1/30 * (1)2 + 1/30 * (2)2

               = (1/30) + (4/30)

               = 5/30

               = 0.167

Question 10

P (2 X 3) = P (X = 2) + P (X = 3)

                     = 1/30 * (2)2 + 1/30 * (3)2

               = (4/30) + (9/30)

               = 13/30

               = 0.433

As per chegg policy an expert is required to solve only the first question, if there are multiple questions. I have completed first 2 questions. Thank you
