The probabilities were the same in the roulette wheel regardless of how many times the wheel was spun. Briefly explain why this is the case.

Step-by-step explanation:

Because there are 38 numbers on a roulette table meaning the probability of any number being landed on is 1/38 however if you chose 2 the chances yours would be chose would be 2/36. every number has an equal chance of being landed on.

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
