Question 588951: Suppose that, for students who are enrolled in college algebra, 71 percent are freshmen, 40 percent are female, and 25 percent are female and are freshmen. Your answers below should be entered as decimals and rounded to three decimal places.
(a) One student will be selected at random. What is the probability that the selected student will be a freshman or female (or both)?
(b) One student will be selected at random. What is the probability that the selected student will not be a freshman?
You can put this solution on YOUR website! Easy when you construct a Venn diagram. Murder otherwise!
a).46+.25+.15=.86 (So .25 is the intersection of the two circles and .86 is the union of the two circles)
.
b)1-.71=.29
