Y = -1
1 - 13(-1)
= 1 - (-13)
= 14
Answer:
30 - (20 ÷ x) ⋅ 4
Step-by-step explanation:
15-4 = 11
11 x 2 = 22
22 + 2/3 = 68/3
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
