Answer: 9/25
Step-by-step explanation
The primes on the spinner are {2,3,5}. The value 1 is not prime.
There are 3 values we want out of 5 values total.
3/5 is the theoretical probability of getting a prime.
(3/5)*(3/5) = (3/5)^2 = 9/25 is the theoretical probability of getting two primes in a row. Each spin is independent of one another.
side note: 9/25 = 0.36 = 36% exactly
