Answer:
0.906
Step-by-step explanation:
Red marbles = 6
Blue marbles = 10
White marbles = 11
8 random marbles are picked out
Probability of:
Red marbles = 2/6 = 1/3
Blue marbles = 3/10
White marbles = 3/11
2/6 + 3/10 = 6x5=30 and 10x3=30
5x2 = 10
10/30
3x3 = 9
9/30
10/30 + 9/30 = 19/30
19/30 + 3/11 = 299/330
299/330 as a decimal is 0.90606
