(a)
Answer to Problem 4E
The probability of freshmen or female is
Explanation of Solution
Given Information:
In French class, 10 freshmen, 8 sophomores, 2 juniors
Female students = 9 freshmen, 2 sophomores, 1 junior
Formula Used:
Two events are mutually exclusive, when they occur at same time.
Calculation:
Find the total members in French class.
Total members in French class
Consider the probability
The event is not mutually exclusive because there are 9 freshmen as female.
Now, find the probability of freshmen or female.
Hence, the probability of freshmen or female is
(b)
Check whether the events are mutually exclusive or not mutually exclusive. Also, find the probability.
(b)
Answer to Problem 4E
The probability of sophomore or male is
Explanation of Solution
Given Information:
In French class, 10 freshmen, 8 sophomores, 2 juniors
Female students = 9 freshmen, 2 sophomores, 1 junior
Formula Used:
Two events are mutually exclusive, when they occur at same time.
Calculation:
Find the total members in French class.
Total members in French class
Consider the probability
The event is not mutually exclusive because there are 6 sophomores as male.
Now, find the probability of sophomore or male.
Hence, the probability of sophomore or male is
(c)
Check whether the events are mutually exclusive or not mutually exclusive. Also, find the probability.

Answer to Problem 4E
The probability of freshman or sophomore is
Explanation of Solution
Given Information:
In French class, 10 freshmen, 8 sophomores, 2 juniors
Female students = 9 freshmen, 2 sophomores, 1 junior
Formula Used:
Two events are mutually exclusive, when they occur at same time.
Calculation:
Find the total members in French class.
Total members in French class
Consider the probability
The event is mutually exclusive because a student cannot be both freshman or sophomore.
Now, find the probability of freshman or sophomore.
Hence, the probability of freshman or sophomore is
