A wheel, which is part of a game at a shopping center is arranged to give 2 tickets 50% of the time, 5 tickets 25% of the time, 10 tickets 23% of the time, and 10 tickets 2% of the time. A player enters the shopping center and spins the wheel. Calculate the expected number of tickets he will get.

The expected number of tickets a customer will get is 4.75.

Step-by-step explanation:

The probability distribution of the number of ticket a wheel at a shopping center is arranged to give is as follows:

X           Probability (p)

2                  0.50

5                  0.25

10                  0.23

10                  0.02

The formula to compute the expected value of a random variable is:

Compute the expected number of tickets a customer will get as follows:

Thus, the expected number of tickets a customer will get is 4.75.

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
