Example of Bayes Theorem

Probability: A kitchen has two cookie jars, J1 and J2. Jar 1 contains 6 ginger snaps and 9 chocolate chip cookies. Jar 2 contains 4 ginger snaps and 8 chocolate chip cookies. The probability of choosing Jar 2 is .6. Given that a ginger snap is drawn, find the probability that it was chosen from Jar 1.
