Probability of getting 4 in single throw = 1/6
so, probability of net getting 4 in single throw = 5/6
probability of getting exactly two fours in five throw = 5C2* (1/6)^2 * (5/6)^3
( Binomial probability )
= 10 * 5^3 / (6^5)
I hope it will help you to understand the concept, feel free to ask if any doubt....
