What is the probability of rolling a pair of six-sided dice five times and getting four 4's?
@Plato this was the other questions I am really struggling with.
This is what I came up with, but I'm not sure if it is correct.
p(x=4) = C(5,4) × (1/36)^4 × (35/36)^5-4
which equals 2.894180045×10^-0.6 ....That looks wrong to me..?
