Question

What is the probability of picking a black marble randomly out of a bag of 7 orange marbles, 10 black marbles, and 10 blue marbles while rolling a 2 on a 6-sided dice at the same time?

Answer 1

10/27. The probability of rolling a 2 on a 6-sided dice is 1/6. The probability of both events occurring at the same time is (10/27) * (1/6) = 5/81.
