First find the possible dices rolls that give you 10, 11, and 12
Gives 10:
5,5
4,6
6,4
Gives 11 or 12:
5,6
6,5
6,6
The dice rolls have 6 * 6 = 36 possible combinations
The probability of getting a 10 is 3/32
The probability of getting an 11 or 12 is 3/32
multiplying those probabilities together with their reward/loss we have:
3/32 * -8 = -3/4
3/32 * 11 = 33/32
to make the game "fair" we need the probable amount of money you can win to be $0, so we can use the equation
-3/4 + 33/32 + (32/32 - 6/32)*x = 0
then you can just solve for x
Answer:
22 rides happened in the hour.
Step-by-step explanation:
The way to solve this if by first dividing the 650 by the 30 then since the answer will be 21.6 that is basically like having 21 full rides then having one more ride a little over half full.
There is a 909 mph gap between the two cars. So if we can divide 3636 by 909 we get 4.
Answer: 4 Hours
B is the correct answer because it is 11-5
Hope this helps :)
3x-8+6x=7
9x-8=7
9x=15
x=9/15
x=3/5
