A bag contains 10 marbles of the same size that are red, yellow, and orange. The probability of picking a red marble is 10%. The probability of picking a yellow marble is 60%. Determine the probability of picking an orange marble from the bag and then classify the probability of picking an orange marble as likely or not likely to occur.

OpenStudy (anonymous):

Heres What I put: 100% is the total of 10 marbles. 10% Of the marbles are red. 60% Of the marbles are yellow. 100 - (10 + 60) =30% The probability of picking a orange marble is 30% and unlikely to occur.

OpenStudy (itsstribe):

red is 10 and yellow is 60 right

OpenStudy (anonymous):

Yes we have to figure out orange.

OpenStudy (itsstribe):
