A bag of marbles contains 2 gold marbles, 10 silver marbles, and 30 black marbles. You decide to play the following game: Random

Rasek [7]

Answer:

-71 cents

Step-by-step explanation:

The total number of balls is 2 + 10 + 30 = 42 balls

The probability of getting gold marble $P_g = 2/42 = 0.04762$

The probability of getting silver marble $P_s = 10/42 = 0.2381$

The probability of getting black marble $P_b = 30/42 = 0.7143$

With the price for each case, we can calculate the expected value of the game by multiplying the price money by the probability and sum them up

$E = 5P_g + 2P_s - 2P_b$

$E = 5*0.04762 + 2*0.2381 - 2*0.7143 = -0.714$ dollar

or -71 cents.

So expect to lose 71 cents everytime you play this game
