Answer:

P(sum is 4 or higher)=11/12

Explanation:

The sample space of rolling two six-sided fair dice is:

(1,1) (2,1) (3,1) (4,1) (5,1) (6,1)

(1,2) (2,2) (3,2) (4,2) (5,2) (6,2)

(1,3) (2,3) (3,3) (4,3) (5,3) (6,3)

(1,4) (2,4) (3,4) (4,4) (5,4) (6,4)

(1,5) (2,5) (3,5) (4,5) (5,5) (6,5)

(1,6) (2,6) (3,6) (4,6) (5,6) (6,6)

number of outcomes having sum 4 or higher=33

total number of outcomes =36

P(sum is 4 or higher)=33/36

=11/12
