1. A person flips a quarter, dime, and nickel. Let x be the number of tails. Complete this probability distribution table.
X 0 1 2 3
2. For the following normal distribution problems find the indicated values. Include a sketch of the appropriate area with each answer.
The area to the left of z = 1.25
The area to the right of z = 1.25
The area between z = 0 and z = 1.25
The area between z = -1.45 and z = 1.25
The z value such that the area to the left of z is 0.9370
The solution shows how to construct the probability distribution table for flipping a quarter, dime, and nickel. It also explains how to use z-score and z-table to find the probability of the normally distributed variable.
