Question

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.

Answer 1

30% is the likelihood of picking a purple marble because 20% of 25 is 5 and 50% of 25 is 12.5 which leaves 7.5 marbles left (purple) and 7.5/25 = .30 which you multiply by 100 to get a percentage of 30
you are less likely to pick a purple marble than a green marble, but you have the least chance of picking a yellow marble
