Len [333]

Using the binomial distribution, it is found that approximately 156 cards must be drawn from the deck before players' tokens move forward 50 times.

<h3>What is the binomial probability distribution?</h3>

It is the probability of <u>exactly x successes on n repeated trials, with p probability </u>of a success on each trial.

The expected number of trials until q successes is:

E_s(X) = \frac{q}{p}

In this problem, the parameters are given as follows:

q = 50, p = 0.32.

Hence:

E_s(X) = \frac{50}{0.32} = 156
