Question

two number cubes are rolled what is the probability that the sum of the numbers rolled is either a 7 or an 11 A.1/4 B.5/18 C.2/9 D.1/2

Answer 1

C) 2/9

Explanation:

rolling 2 number cubes produces 36 possible outcomes (6 options per each cube)

outcomes that produce a 7:

1+6

6+1

2+5

5+2

3+4

4+3

outcomes that produce an 11:

5+6

6+5

probability of 7 OR 11 is 6/36 + 2/36 = 8/36 or 2/9
