Using the binomial distribution, it is found that there is a 0.2373 = 23.73% probability that she does not wait for more than 10 minutes on all 5 roller coasters she rides at the amusement park.
<h3>What is the binomial distribution formula?</h3>
The formula is:
The parameters are:
x is the number of successes.
n is the number of trials.
p is the probability of a success on a single trial.
The values of the parameters are given as follows:
n = 5, p = 0.25.
The probability that she does not wait for more than 10 minutes on all 5 roller coasters she rides at the amusement park is P(X = 0), hence:
