Four marbles are drawn from the box at the same time. 23C4 = 8855 total possiblities
A. P(all same color) = 8C4+4C4+5C4+6C4/23C4 = 91/8855  Yes!
B. P (non are blue) = 17C4/23C4= 2380/8855   Yes!
C. P (one of each) ={{{ 8C1*4C1*5C1*6C1/23C4)}}} = 8*4*5*6/(23C4)= 960/8855  Yes!
D. P (More than 2 green) = 8C3*15C1=840 (3 yellow)
 8C4*15C0=70 (4 yellow)
 840+70/23C4= 910/8855  Yes!
Good work!
