Question

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.

Answer 1

30%

not likely

Explanation:

P(orange) = 100 - 10 - 60

= 30%

Less likely or not likely

Answer 2

30% not likely

Explanation:

We have 10 marbles

The probability must equal 100%

10% red

60% yellow

----------------

70 %

That leaves 30% for orange

Orange is 30%

This is less than 50% so it is not likely to occur
