The answer is negative 1. You divide the data set into 2 parts. Find the median of each and subtract the left side from the right
The expected value of the game is the mean value of the game
The expected value of the game is $1
<h3>How to determine the expected value?</h3>
There are 13 spades in a deck of card of 52
So, the probability of selecting a spade is:
P(Spade) = 13/52
Simplify
P(Spade) = 1/4
Winning = $7
The probability of not selecting a spade is:
P(Not spade) = 1 - 1/4
Simplify
P(Not spade) = 3/4
Lose = $1
The expected value of the game is:

This gives

Simplify

Evaluate

Hence, the expected value of the game is $1

Answer:
Alright well solve for y by simplifying both sides of the equation then isolating the variable
Exact form: y = - 13/2
Decimal form: y = - 6.5 Hope this helps have a nice day :)
