Answer:
The answer to the question is B.
Wait, I'm sorry, correction: a = 15, b = 7, c = 5, d = 10, e = 12.
Step-by-step explanation:
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
