Given a roll of a six-sided die, determine the following: a. Find the probability distribution X and P(X). b. Find the expected value E(X) and the standard deviation, σ.

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632

b. 153 students do not participate in sports and seventy-five 12th graders were surveyed
