Write 27 as a product of primes.
Use index notation where appropriate.

3 x 3 x 3 = 3^3

Step-by-step explanation:

27 as a product of it's primes = 3 x 3 x 3 In index notation= 3^3

correct

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
