Using the binomial distribution, we have that you would expected to draw a face card 8 times.
<h3>What is the binomial probability distribution?</h3>
It is the probability of exactly <u>x successes on n repeated trials, with p probability</u> of a success on each trial.
The expected value of the binomial distribution is:
E(X) = np
For this problem, the parameters are given as follows:
- n = 35, as the experiment will be repeated 35 times.
- p = 0.2308, as of the 52 cards, there are 12 faces, hence 12/52 = 0.2308.
Then the expected value is found as follows:
E(X) = np = 35 x 0.2308 = 8
You would expected to draw a face card 8 times.
