Question

Luanda played a game in which she could win 10 points with a probability of 0.2. There is a 0.8 probability that she will not win any points. How many points can Luanda expect to win?

A) 2
B) 4
C) 6
D) 8

Answer 1

Luanda can expect to win 2 points.

Step-by-step explanation:

To calculate the number of points Luanda can expect to win, we multiply the number of points she can win (10) by the probability that she will win those points (0.2). We can express this as:

Expected Points = 10 x 0.2 = 2

Therefore, Luanda can expect to win 2 points.
