Question

a player spins two spinners. the outcome of each spinner is 1, 2, or 3. each outcome is equally likely. define the random variable x to be the maximum of the two numbers on the spinners. what is e[x]? group of answer choices 2/3

Answer 1

2

Explanation:

E(x) is the sum of px, that is the sum of probabilities times the value associated with it.

we calculate px as:

1×1/3=1/3

2×1/3=2/3

3×1/3=1

the sum is 1/3+2/3+1=2.

so, the expected value is 2
