Title: Suppose that W is a random variable. Given that P(W 3) = 0.625, find P(W > 3).
Post by: sjones on Apr 7, 2020

Question 1

Use the special addition rule and the following probability distribution to determine P(6 < X ≤ 8).
 x                5          6          7          8          9          10          11    
P(X = x)    0.05    0.05     0.20     0.15     0.15      0.10        0.30
◦ 1.00
◦ 0.35
◦ 0.40
◦ 0.45

Question 2

Suppose that W is a random variable. Given that P(W ≤ 3) = 0.625, find P(W > 3).
◦ 0
◦ 0.375
◦ 0.625
◦ 3
