The probability would be 1/4. The probability of rolling an even number on each die is 1/2. Since there are two dice you would multiply the probability of each die together. 1/2*1/2=1/4. The reason you would this is because you could roll two odd numbers that equal an even number such as 3 and 5.

Answer:

Step-by-step explanation:

The question says,

A roulette wheel has 38 slots, of which 18 are black, 18 are red,and 2 are green. When the wheel is spun, the ball is equally likely to come to rest in any of the slots. One of the simplest wagers chooses red or black. A bet of $1 on red returns $2 if the ball lands in a red slot. Otherwise, the player loses his dollar. When gamblers bet on red or black, the two green slots belong to the house. Because the probability of winning $2 is 18/38, the mean payoff from a $1 bet is twice 18/38, or 94.7 cents. Explain what the law of large numbers tells us about what will happen if a gambler makes very many betson red.

The law of large numbers tells us that as the gambler makes many bets, they will have an average payoff of which is equivalent to 0.947.

Therefore, if the gambler makes n bets of $1, and as the n grows/increase large, they will have only $0.947*n out of the original $n.

That is as n increases the gamblers will get $0.947 in n places

More generally, as the gambler makes a large number of bets on red, they will lose money.

Solve for x: 3(x + 1) = −2(x − 1) + 6.
monitta
<span> 3( x + 1 ) = - 2 ( x - 1 ) + 6 </span>

<span>1) Clear the parentheses by distributing the 3 and the - 2 </span>
<span>When you have done that, this is what you will get: </span>
<span>3x + 3 = - 2x + 2 + 6 </span>

<span>2) Combine the like terms on the right </span>
<span>You will get this: </span>
<span>3x + 3 = - 2x + 8 </span>

<span>3) Add 2x to both sides to collect all the x terms together on the same side </span>
<span>When you finish doing that, you will have </span>
<span>5x + 3 = 8 </span>

<span>4) Subtract 3 from both sides to isolate the 5x term alone on one side </span>
<span>You will get </span>
<span>5x = 5 </span>

<span>5) Divide both sides by 5 to isolate x </span>
<span>x = 1 <-- answer</span>
