Question

A bag contains 20 marbles of the same size that are blue, green, and red. The probability of picking a blue marble is 20%. The probability of picking a green marble is 50%. Determine the probability of picking a red marble from the bag and then classify the probability of picking a red marble as likely or not likely to occur.

Answer 1

The probability of picking a red marble is 30%. 30% of 20 is 6 red marbles. Therefore, picking a red marble is unlikely. Since the blue and green marbles equal 70% of the probability.
