Answer:
0.064. same as 8/125
Step-by-step explanation:
Probability is the ratio of the number of possible outcome to the total outcome.
Given that Sixty percent of the marbles in a bag are blue
The probability of picking a blue marble
p(b) = 60% = 3/5
The probability of not picking a blue marble
np(b) = 1 - 60%
= 1 - 3/5
= 2/5
Hence where 3 marbles are picked and replaced, the probability of not picking a blue marble
= 2/5 * 2/5 * 2/5
= 8/125
= 0.064
