Answer:
Lose $0.05
Step-by-step explanation:
There are 38 possible spots on the roulette wheel (numbers 1 to 36, 0 and 00).
If the player can choose four numbers on single $1 bet, his chances of winning (W) and losing (L) are as follows:

The expected value of the bet is given by the probability of winning multiplied by the payout ($8), minus the probability of losing multiplied by the bet cost ($1)

On each bet, the player is expected to lose 5 cents ($0.05).
You are adding a negative and a positive. It is like subtracting 2.1 from 3.26. Because 2.1 is negative, whenever you add it to a number, you actually subtract. To do this:
3.26 + (-2.1) is like 3.26 - 2.1
3.26 - 2.1 = 1.16
The answer to the question is 1.03
Answer:
2.25 hours, or 2 hours and 15 minutes.
Step-by-step explanation:

There is no mode in these scores listed.
Mode is if a number appears twice. Like 4 and 4.
