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
Yes, 13 is the remainder.
See dat pic for full solution.
n=# of nickels
q=# of quarters
$12 is 1200 cents
5n+25q=1200
n=q
substitute q for n or n for q
5q+25q=1200
30q=1200
q=1200/30
q=40 quarters and therefore n=40 nickels
40 quarters is $10 and 40 nickels is $2, therefore you have $12
