3.E- 3/10 or 30% To get this answer , you must first find out the T.P.O.(Total Possible Outcomes). In this case ther are 10. In the diagram there are 3 Favorable outcomes. 3Black, 1White, and 6Striped. Since there are only 3 blacks the fraction is 3/10. The percentage is 30%.
3.A-Refer to lines one and two if you cannot remember the T.P.O. There are 3 blacks out of ten so the answer is 8/10. Simplified to 4/5. The percentage is 80%.
3.R- Black and white add up to 4 so the answer is 4/10. Simplified to 2/5. The percentage is 40%.
3.S-7 striped out of ten. 7/10. 70%.
3.E2-Not white equal to 9 /10. 90%
3.M-Ther are no yellow so the answer is 0/10. 0%.
Now if there happened to be fifteen marbles and the favourable outcomes were 8 striped, 5 black, and 2 whites, what would be the answer to number one? Two? Three?
Black would now be 5/15 or 1/3 with a percentage of 33.3%
Not black would be 10/15 or 2/3 or 66.6%
Black or White would now be 7/15 or 46.6%
