Answer:
–0.5
Step-by-step explanation:
Expected value is found by multiplying the probabilities of each roll by the amount won or lost with each roll.
The odd rolls are 1, 3 and 5. The probability of rolling a 1 is 1/6, and the value is 1; this gives us 1/6(1) = 1/6.
The probability of rolling a 3 is 1/6, and the value is 3; this gives us 1/6(3) = 3/6.
The probability of rolling a 5 is 1/6, and the value is 5; this gives us 1/6(5) = 5/6.
Rolling any even number gives us the same value. The probability of rolling an odd number is 3/6, and the value is -4; this gives us 3/6(-4) = -12/6.
Together we have
1/6+3/6+5/6-12/6 = 4/6+5/6-12/6 = 9/6-12/6 = -3/6 = -0.5

Step-by-step explanation:
Answer:
1. 12
2. 10
3. 18
4. 6
Step-by-step explanation:
In Mathematics, substitution is a method used for solving algebraic equation by inputing the values of a given variable.
1) 4x - 4, when x = 5
4(4) - 4 =
16 - 4 = 12
2) 7 + m -2, when m = 5
7 + 5 - 2 =
12 - 2 = 10
3) 5+5h + 3, when h = 2
5 + 5(2) + 3 =
5 + 10 + 3 = 18
4) 3n - 6, when n = 4
3(4) - 6 =
12 - 6 = 6
