Question

Wyatt buys a bag of cookies that contains 4 chocolate chip cookies, 7 peanut butter cookies, 7 sugar cookies and 7 oatmealcookies. What is the probability that Wyatt reaches in the bag and randomly selects an oatmeal cookie from the bag, eats it, thenreaches back in the bag and randomly selects a peanut butter cookie?

Answer 1

Chocolate chips cookies = 4

Peanut butter cookies = 7

Sugar cookies = 7

Oatmeal cookies = 7

Total cookies = 4 + 7 + 7 + 7 = 25

We want to find probability without replacement

Therefore, the answer is

`p(OatmeatAndPeanutButtter)=(49)/(600)`
