Stacy rolls a pair of six-sided fair dice. the probability that the sum of the numbers rolled is either a multiple of 3 or an even number is , and the two events are exclusive

5/9

Step-by-step explanation:

Let the probability of getting a multiple of 3 is "A"

Let the probability of getting an even number is "B"

Total number of outcomes=36

Total number of favourable outcomes  of either a multiple of 3 or an even number are

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

That is we have 20 favourable outcomes

Hence,

Therefore, after substituting the values we get

After simplification we will get

a) what number, when added to negative four, is equal to negative five?
