Use the data below for questions 2-3

A random sample was taken of 3055 liberal arts students of how many math courses they took in during their undergraduate experience. The data below represents a random variable x of a finite population, and has the following frequency distribution:

x	1	2	3
frequency	1250	1020	785

Suppose a data point is randomly selected from the population. Let X denote the value of the variable x for the member obtained.

What is the probability that Liberal Arts students will take two more more math classes? The event that X takes on a value of at least 2 is denoted as {X 2}.

Group of answer choices

P(X2) = 0.743
