Answer 1

Question

Definition Definition Middle value of a data set. The median divides a data set into two halves, and it also called the 50th percentile. The median is much less affected by outliers and skewed data than the mean. If the number of elements in a dataset is odd, then the middlemost element of the data arranged in ascending or descending order is the median. If the number of elements in the dataset is even, the average of the two central elements of the arranged data is the median of the set. For example, if a dataset has five items—12, 13, 21, 27, 31—the median is the third item in ascending order, or 21. If a dataset has six items—12, 13, 21, 27, 31, 33—the median is the average of the third (21) and fourth (27) items. It is calculated as follows: (21 + 27) / 2 = 24.

In American roulette, the wheel contains the numbers 11 through 3636, alternating between black and red. There are two green spaces numbered 00 and 0000. A player places a bet of $0.50$⁢0.50 on red to play the game. If the ball lands on red, the player gets a $0.50$⁢0.50 for winning and receives the money back. If the ball does not land on red, then the player simply loses the $0.50$⁢0.50 placed on the bet. If the player places the same bet on red 99 times, what is the player’s expected winnings? Round your answer to the nearest cent.
