Answer:
1/20
Explanation:
Total number of marbles= 5 + 3 + 4 + 6 + 2 = 20
Probability of picking a brown marble P(Brown) = 5/20 = 1/4
Probability of picking a yellow marble P(Y) = 3/20
Probability of picking a blue marble P(B)= 6/20 = 3/10
Probability of picking an orange marble P(O)= 2/20= 1/10
Probability of picking a red marble P(R)= 4/20= 1/5
Since the marbles were chosen with replacement;
P(Br) and P(R) = 5/20 × 4/20 = 20/400= 2/40= 1/20
