A man shares his money to on his two sons

Ronch [10]

Answer:

$150 is the amount of share Kwame has, and he has 3 shares.

Step-by-step explanation:

Kofi and Kwame's shares have a ratio of 2:3.

Kofi's share (2) is 100 dollars.

First, divide 100 with 2, to find the amount each share is worth:

100/2 = 50

One share = $50.

Now, note that Kwame has 3 shares. Multiply 3 with 50

3 x 50 = $150

$150 is the amount of share Kwame has, and he has 3 shares.

Consider the following game: Roll a fair 6-sided die. You win if the result is greater than 4; otherwise, you lose. To play, you

dalvyx [7]

Answer:

-$1.33 or lose $1.33

Step-by-step explanation:

In this game, there are two possible outcomes.

- There is a 2 in 6 chance (rolling a 5 or a 6) that you win $8.

- There is a 4 in 6 chance (rolling a 1, 2, 3 or a 4) that you win nothing.

Note that for any outcome, you start off paying $4 to play.

The expected value of this game is:

$E(X) =\frac{2}{6} *\$8+\frac{4}{6}*\$0-\$4\\E(X) = -\$1.33$

You are expected to lose $1.33 per play.
