74. A friend devises a game that is played by rolling a single six-sided die once. If you roll a 6, he pays you $3; if you roll a 5, he pays you nothing; if you roll a number less than 5, you pay him $1. Compute the expected value for this game. Should you play this game

The expected value is -$0.17

Since it gives a negative expected value, the game is not favorable and should not be played

Step-by-step explanation:

Here, we want to calculate the expected game value and decide if the game is worth playing

Probability of rolling a six is 1/6

Probability of rolling a 5 is 1/6

Probability of rolling a number less than 5 is 4/6 = 2/3

So the only way to win is rolling a six

The expected value is thus;

1/6(3) - 0(1/6) - 2/3(1)

= 1/2 - 2/3

= -$0.17

Since the game gives a negative expected value, it is not favorable and should not be played

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.

the factors of 15 are 1, 3, 5, and 15.

hope that , fam!
