A cookie jar has 3 chocolate chips, 2 peanut butter, and 5 oatmeal raisin cookies. If Mo chooses a cookie, does not replace it, then chooses another, what is the probability that he chooses a peanut butter then a chocolate chip cookie?

2 peanut butter /10 total cookies x 3 chocolate chip /9 total cookies = 6/90 = 1/15

1/15 chance

Step-by-step explanation:

1:5, 1:3

Step-by-step explanation:

a cookie jar has 10 total cookies

peanut butter: the probability that he chooses a peanut butter is 2:10 or 1:5

now the cookie jar only has 9 because he took one and didn't replace it

chocolate chip cookie: the probability that he chooses a chocolate chip cookie is 3:9 or 1:3

there are infinitely many solutions.

a.) list the factors of 40.

1/2/4/5/8/10/20/40

b.) list the factors of 40 that represent the number of cans that could be on each shelf.

5

c.) how many different arrangements of cans are possible?

just one because if you put more on one shelf you will go way over 40 and the cabinet will probably break.

d.) what are the possible arrangements of the cans?

put 5 cans on each self to reach 40 cans in total.

e.) which arrangement uses all the shelves?

5 because you can put 5 cans on each shelf, and since there are 8 shelfs you are equally going to get 40 cans.
