Question

An experiment consists of rolling two fair dice and adding the dots on the two sides facing up. What is the probability that the sun of the dots is 7 or 11

Answer 1

4 /9

Explanation:

Given that :

Number of faces on a number cube = 6

Sample space for two number faces = 6² = 36

Probability that sum of a roll is 7 or 11:

Probability = number required outcome / Total possible outcomes

Number of Required outcome = number of 7's + number of 11's

Number of 7's = 6

Number of 11's = 2

Total = 8

Total possible outcomes = 6² =36

P(sum of 7 or 11 ) = 8 /36 = 4 /9
