To find the probability of picking a purple marble, we first add the probabilities of picking a yellow and green marble and subtract the total from 100% (since the marbles are either yellow, green, or purple).
Probability of picking a yellow marble = 20%
Probability of picking a green marble = 50%
Probability of picking a purple marble = 100% - (20% + 50%) = 30%
Therefore, the probability of picking a purple marble is 30%. Since it is not the highest probability among the three options (green marble has a higher probability), we classify the probability of picking a purple marble as not likely to occur.
So, the answer is:
30%; not likely
A bag contains 25 marbles of the same size that are yellow, green, and purple. The probability of picking a yellow marble is 20%. The probability of picking a green marble is 50%. Determine the probability of picking a purple marble from the bag and then classify the probability of picking a purple marble as likely or not likely to occur.
