Question

Suppose a bag contains many marbles, 50% of which are white. You draw 9 marbles from the bag with replacement.
(a) Find the probability that you draw exactly 4 white marbles.
0.13
0.246
0.538
0.719
(b) Find the expected value of the number of white marbles.
2.04
4.5
6.62
7.09

Expert Solution

Step 1: Given

Proportion of white marbles =50% (P=0.5)

n=9

The marbles are drawn with replacement which means probability of getting white will remain same in every draw,

therefore we can use binomial distribution.

Step by step
