Eli has 7 black pens and 5 blue pens in his desk drawer. He also has 3 yellow highlighters, 2 green highlighters, and 5 pink highlighters in his pencil case. If he chooses one pen and one highlighter without looking, what is the probability that he will get a black pen and he will not get a green highlighter?

The probability of choosing a black pen is 7/15, and the probability of not choosing a green highlighter is 10/12 (since there are 2 green highlighters out of a total of 12 highlighters).

Therefore, the probability of both events happening is (7/15) x (10/12) = 117/1000.
