Answer
1/46656
Step-by-step explanation
Let A, B and C represent Cole, Matthew and Chris respectively.
Number of flavors, n(s) = 36
Since they randomly chose 3 flavors, so each of them chooses 1 flavour,
⇒ P(A) = P(B) = P(C) = 1/36
The probability that the 3 they choose will consist of each of their favorite flavors =
P(A) x P(B) x P(C) -----Independeent events
1/36 x 1/36 x 1/36
= 1/46656
The probability that the 3 they choose will consist of each of their favorite flavors is 1/46656
