Answer:
And using the probability mass function we got:
Step-by-step explanation:
Previous concepts
The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".
Solution to the problem
Let X the random variable of interest, on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
And we want to find this probability:
And using the probability mass function we got:
Answer:
40 miles per hour
Step-by-step explanation:
Driver a could be going 50 miles per hour
Driver c could be going 30 miles per hour
40 miles per hour is in the middle so that could be your answer
