Answer:
Step-by-step explanation:
Let X = amount you can win at this game (# of dollars you can win)
x = (0, -2, 6, 10, 15)
- P(X=0) = P(probability of picking a diamond) = 13/52 = .25
- P(X=-2) = P(probability of picking a heart) = 13/52 = .25
- P (X= 6) = P(probability of picking a spade) = 13/52 = .25
- P(X=10) = P(probability of picking a club) = 12/52 ≈ .231
- P(X=20) = P(probability of picking the ace of clubs) = 1/52 ≈ .019
Probability Distribution of X
x p(X = x) Decimal
0 13/52 0.25
-2 13/52 0.25
6 13/52 0.25
10 12/52 0.231
15 1/52 0.019
Total 52/52 1.00
762,872 that should be your answer if I’m correct
2x+7y=4
+(-2x-8y=-2)
------------------
0x-y=2
-y=2 (this is the result of adding the two equations)
But...
y=-2
2x+7(-2)=4
x=9
