Question

A bag contains 3 red marbles and 8 blue marbles. A marble is drawn from the bag, the color recorded, then the marble is put back into the bag. This process is repeated ten times, and we are interested in the number of blue marbles drawn. What would be the probability of success in this experiment

Answer 1

Answer:

0.0414

Step-by-step explanation:

Total number of marbles= 8+3= 11

8 blue and 3 red

Marbles are picked with replacement until 10 marbles are selected.

Probability of number of blue marbles choosen in 10 pick with replacement out of 11 marbles= ((8C1/11C1))^10

=(8/11)^10

=0.72723^10

= 0.0414
