Answer:  B)  4/55

============================================

Work Shown:

Define the events

A = she picks jeans

B = she picks a sweatshirt

P(A) = (# of jeans)/(# of skirts or pants)

P(A) = 4/(3+1+2+4)

P(A) = 4/10

P(A) = 2/5

P(B) = (# of sweatshirts)/(# of shirts, sweatshirts or sweaters)

P(B) = 2/(3+5+2+1)

P(B) = 2/11

P(A and B) = probability she picks jeans and sweatshirt

P(A and B) = P(A)*P(B) ... works because A and B are independent

P(A and B) = (2/5)*(2/11)

P(A and B) = (2*2)/(5*11)

P(A and B) = 4/55
