Solution
0.30 ( AS GIVEN IN THE DATA TABLE)
THIS WILL INCLUDE ALL THE PROBABILITY FOR CASES LESS THAN AND EQUAL TO 75 EHICH WILL INCLUDE X = 25,50,75
HENCE P(25)+P(50)+P(75) = 0.20+0.40+0.30 = 0.90
C)P(X > 50) = THIS WILL INCLUDE CASE FOR X > 50 WHICH INLCUDE X = 75,100
S00 P(75)+P(100) = 0.30+0.10 = 0.40
D)P(X < 100) = THIS WILL INVLUDE THE CASES FOR X<100 THEREFORE INLUDE X = 25,50,75
P(25)+P(50)+P(75) = 0.90
| a. | P(X = 75) = |
