It's Sunday morning. I am at home, sipping a cup of espresso and scratching my head over my exams. My students exams, that is. I was informed on Friday afternoon that my 3 final exams are due on Monday in the form of 40 multiple choice questions each. Gloops.

Since I always aspire to sprinkle sticky stars over their little heads, I am preparing such problems:

"In your drawer, there are 3 pairs of white socks, 5 pairs of blue socks and 1 pair of yellow socks. If you pick two socks out of the drawer (one after the other without replacing the first one), what is the probability of getting two matching socks?"

Enjoy your weekend, fellow maths heads :) Share the love!
