24 balls and choosing 5; the denominator is 24C5
a. The numerator is 6C3*8C2=15*28=420. The denominator is 42,504, probability is 0.01
b. The numerator is 10C4*14C1+10C5=2940+252=3192; the probability is 0.075
c. The numerator is 10C5 + 8C5=252+56=308; the probability is 0.007
d. 8C3*16C2+8C4*16+8C5=56*120+70*16+56=6720+1120+56=7896 numerator: probability is 0.186
