II Find each probability if you choose one card at random.

#7 P(striped) First you have to find the total possible outcomes which is 8. There are 3 striped squares so the answer is 3/8

#8 P(white) The total possible outcomes for all of these questions is 8 and there are 4 white so the answer is 4/8 , but reducing it will make it 1/2.

#9 P(shaded) there is 1 shaded box P = 1/8

#10 P(white or shaded) there are 4 white boxes and one shaded P = 5/8

#11 P(striped or white) there are 3 striped and 4 white boxes P = 7/8

#12 P(striped or shaded) there are 3 striped and one shaded box P = 4/8 reducing it will make it 1/2

#13 P(not striped) there are only 3 striped, so 3-8=5 P = 5/8

#14(not white) there are only 4 white so 4-8=4 P = 4/8 reducing it will make it 1/2

#15 P(striped or white or shaded) there are 3 striped 4 white and one shaded that means that the answer is 8/8 reducing it will make it 1/1
