If a positive number less than twenty is divisible by 5, then it is an odd number???

Yes, because every number under 20 that can be divided by 5 is 15, 10, and 5 and two are odd numbers and only one is an even number.

Step-by-step explanation:

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
