What is the probability of rolling two normal six-sided dice and getting exactly one six?

A) 1/36
B) 1/6
C) 5/18
D) 11/36
E) 1/3

Possible pairs having exactly one six are (1,6), (2,6),(3,6),(4,6),(5,6),(6,1)...(6,5) = 10 pairs
Total number of possible pairs = 6*6 = 36

Therefore, probability of getting exactly one six = $$\frac{10}{36} = \frac{5}{18}$$

We can get six either on dice 1 or on dice 2 so:
prob(of getting six) = 1/6
prob(of not getting six) = 5/6

prob(exactly one six) = (six on dice 1 and some other no. on dice 2) or (six on dice 2 and some other no. on dice 1)
= (1/6 * 5/6) + (1/6 * 5/6)
= 5/36 + 5/36
= 5/18

Ans. C) 5/18

(1/6)*(5/6)*2! = 5/18
