Okay so I am lost. I understand that the probability of an event is

the # of ways an event can occur over the total # of possible outcomes.

I need some explaining done. Please

**Carrie**, Sunday, March 7, 2010 at 1:02amWould the total possible outcomes be 17?

The number of evens would be 10 and the multiply of 3 is 7. So 10 and 7 together is 10.

**Reiny**, Sunday, March 7, 2010 at 7:43amList the numbers from 1 to 21 which are either even or multiples of 3:

2,3,4,6,8,9,10,12,14,15,16,18,20,12

I count 14, not 17.

Prob(event as stated) = 14/21 = 2/3
