Natasha_Volkova [10]

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:

P(W) = \frac{4}{38} \\P(L) = 1-P(W) = 1-\frac{4}{38} \\P(L) = \frac{34}{38}

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)

EV=\frac{4}{38}*\$8 -\frac{34}{38}*\$1\\EV= -\$0.05

On each bet, the player is expected to lose 5 cents ($0.05).

How do I perform this operation(-2.1) + (3.26)
Dmitry [639]
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
