Answer:
$2.56
Step-by-step explanation:
P(7 or 11) = 8/36 = 2/9
P(winning 20-2 = 18) = 2/9
P(2 or 12) = 2/36 = 1/18
P(winning 2-2 = 0) = 1/18
P(others) = 26/36 = 13/18
P(winning 0-2 = -2) = 13/18
Expected win
= 18(2/9) + 0(1/18) - 2(13/18)
= $23/9 or $2.56

Answer:
The value of P(A ∪ B) is 0.682 to the nearest thousandth
Step-by-step explanation:
The addition rule of probability is:
P(A ∪ B) = P(A) + P(B) - P(A ∩ B), where P(A ∪ B) is probability A or B , P(A ∩ B) is probability A and B
∵ P(A) = 0.33
∵ P(B) = 0.6
∵ P(A ∩ B) = 0.248
- Substitute these values in the rule above
∴ P(A ∪ B) = 0.33 + 0.6 - 0.248
∴ P(A ∪ B) = 0.682
The value of P(A ∪ B) is 0.682 to the nearest thousandth
