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% and not likely

Explanation:

if you add the 50% and the 20%, you get 70%, and since the 25 is like 100%, you subtract 70% from 100%, giving you 30%, and since 30% is less than 50%, or 1/2, it is not likely to pick a purple marble.

Answer 2

20% + 50% = 70%

100% - 70% = 30%

The probability of picking a purple marble from the bag is 30% which is not likely.
