Question

A cookie jar contains 2 chocolate chip cookies, 5 oatmeal raisin cookies, and 3 sugar cookies. event a = drawing a chocolate chip cookie on the first draw event b = drawing a sugar cookie on the second draw if two cookies are drawn from the jar, one after the other and not replaced, what is p(a and
b.expressed in simplest form?

Answer 1

2 + 5 + 3 = 10 total cookies

event A picking a chocolate chip cookie = 2/10 reduced to 1/5 probability

event B picking a sugar cookie after 1 cookie was already picked = 3/9 reduced to 1/3

probability of both: 1/5 x 1/3 = 1/15 probability
