A study showed that 25% of the students drive themselves to school. Based on the suggested probability, in a class of 18 students, what would be the probability that at least 6 students drive themselves to school? (CDF) A) 0.139
B) 0.283
C) 0.717
D) 0.861

B) 0.283

Step-by-step explanation:

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.

25% of the students drive themselves to school.

This means that

Class of 18 students

This means that

What would be the probability that at least 6 students drive themselves to school?

This is

In which

So

Closest option is B, just a small rounding difference.
