Explanation / Answer

Question 2:

Total students = 62
Probability that a student is female, P(F) = 43/62 = 0.6936
Probability that a student takes only web classes, P(W) = 13/62 = 0.2097
Probability that a student is female and takes web classes, P(FW) = 8/62 = 0.129

The probability that a randomly selected student is female or takes only web classes, P(F or W) = P(F) + P(W) - P(FW) = 0.6936 + 0.2097 - 0.129 = 0.7743

Question 3.

the probability that a randomly selected student is male and takes only traditional classses = 11/62 = 0.1774

Question 4.

5/62 < 8/62 so females are more likely to take only web clases

Question 5

There are 5 blue balls and total 35 balls in the bag

Probability that a ball selected is blue p = 5C1/35C1 = 0.1429

Required probability that 3 selected balls are blue is p^3 = 0.1429^3 = 0.0029

Question 6

There are 4 blue balls and total 35 balls in the bag

Probability that a ball selected is orange p = 4C1/35C1 = 0.1143

Required probability that 3 selected balls are orange is p^3 = 0.1143^3 = 0.0015
