Question 935482: Two dices are thrown at a time. What is the probability that the sum of the numbers on two dice is 10 or the product of two numbers is >= 25 or both. Found 2 solutions by oscargut, ewatrrr:Answer by oscargut(2103) (Show Source):
You can put this solution on YOUR website! P(sum 10) = 3/36
P(product >=25) = 4/36
P(sum 10 and product >=25) = 1/36
So the required probability is: (3+4-1)/36 = 1/6
Answer: 1/6

P(A or B) = P(A) + P(B) - P(A and B)
P( x = 10 0r x >= 25) = = 1/6
