Question 8. Using the Marijuana by Gender table from Module 4b which is replicated below,What is the probability that a user will be female given chronic usage, i.e. P(Female|Chronic)?

Gender	Marijuana Usage	Row Total
Never	Tried	Chronic
Male	505	165	25	695
Female	105	35	10	150
Column Total	610	200	35	845

Question 9. In Module 4b, we saw that males and females were proportionally the same in having never used marijuana and occasionally used marijuana, but that females had nearly twice the rate of chronic usage than males, 6.7% to 3.6%? What other factorsmight explain the gender difference in chronic marijuana usage? Do you thinkthis result mightbe due to chance alone? Why or why not?
