STC1102 Study Guide - Midterm Guide: Central Limit Theorem, Rational Number, Disjoint Sets

A red die is tossed and then a green die is tossed. What is the probability that the red die shows an even number or the green die shows an even number?

Make sure your answer is reduced.

 

 

 

Hint: The two events are not mutually exclusive. So to the find the probability of the union, use: P(A or B)=P(A)+P(B)-P(A and B)

This probability distribution shows the typical distribution of the number of shoes in a teenager's closet.

Using this distribution, find the probability that a teenager has fewer than 3 pairs of shoes in their closet.

 

p = [?]

 

This probability distribution shows the typical grade distribution for a Geometry course with 35 students.

Find the probability that a student earns a grade of B.

p=[?]

Enter a decimal rounded to the nearest hundredth.
