There are 24 students in the class. if 12 of them enrolled to the french courses, 13 of them to the spanish and 7 of them take neither, what is the probability that a randomly-chosen student from this group is taking only the french class?

Talia grouped the terms and factored out the gcf of the groups of the polynomial 15x2 – 3x – 20x + 4. her work is shown below. (15x2 – 3x) + (–20x + 4) 3x(5x – 1) + 4(–5x + 1) talia noticed that she does not have a common factor. what should she do?
