Answer:
m = (f(4) - f(2)) / (4 - 2)
m = (24 - 10) / (4 - 2)
m = 14 / 2
m = 7
5:7 (pencils to pens)
7/12 chance that a pen from the first box will be selected.
4:4 (colour pencils to crayons)
4/8 = 1/2 chance that a crayon from the second box will be selected.
The probability of picking both:
7/12 * 1/2 = 8/24 = 1/3
