SOLUTION: Two dice are biased so that the probability of getting a six on each die is 0.2. The two dice are rolled. I found P(two 6s)= 0.04 but I can't find P(exactly one 6)

Two dice are biased so that the probability of getting
a six on each die is 0.2.

The two dice are rolled.
I found P(two 6s)= 0.04
OK
--------------------
but I can't find P(exactly one 6)
Binomial with n = 2 and p = 0.2 and q = 0.8
---
P(x= 1) = 2C1(0.2)^1*0.8^1
---
= 2*0.2*0.8
---
= 0.32
