Question

The probability distribution of a game is shown in the table. Find the expected number of points won per play. Round to the nearest tenth if needed.

a) 5.7 b) 4.5 c) 4.7 d) 5

Answer 1

4.5

Explanation:

I just did this lesson and i just guessed, but i got it wrong and it said the answer was 4.5. basically, you multiply the fractions and the number value first,(like 1/6 X 0) and you do that to all of them. and then you add up all your answers, simplify them and put it in decimal form. and you get 4.5. hopefully that made enough sense.
