There are 11 cans of cola, 28 cans of orange juice, 15 of ginger rale, and 46 of rootbear. these cans are all in the same shapes and sizes. if one can is selected at ramdon what is the probl that the soda is ginger ale, rootbear or cola?

the converse is easier to determine 100 - 28 = 72

8. amistre64

yes; you wanna know what is the chance that youl get any of those 3

9. amistre64

since there was 100 to choose from; it makes it easier to just add the number

72 becomes the bottom number

11. anonymous

now do u subtract 72 from 100

12. amistre64

72 out of 100 72/100

13. anonymous

and to reduce that you device them

14. amistre64

28 cans are not gingerbearcola sooo 1 - 28/100 is the same answer as 72/100

15. amistre64

yes

16. amistre64

36/50 = 18/25 ...
