a)

P(Two red) = P(Red)*P(Red after one is drawn) = (5/10)(4/9) = 20/180 = 1/9

b)

P(One blue and one yellow) = P(blue) * P(yellow after one draw) = (3/10)(2/9) = 6/90 = 1/15

c)

P(Two yellow) = P(yellow)*P(yellow after one is drawn) = (2/10)(1/9) = 2/90 = 1/45

d)

P(One red and one blue) = P(red) * P(blue after one draw) = (5/10)(3/9) = 15/90 = 1/6
