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

For starters... you have 10 marbles.

10% is red and since you have 100% total, you have 1 red marble.
Same for orange. There is 6 orange marbles because 60% of 100%.

Add these two (6 + 1)

\[6+1\]Equalling seven, and since you have 10 marbles, what is 10 - 7?

\[10-7\]

Answer 2

And when you get that, picking an orange marbe (60% chance) as likely or not, you would get what? Remember this...

10% or 1 for red marble
60% or 6 for orange marble
100% or 10 for all marbles

Answer 3

40%?

Answer 4

No. 10 is 100%. You have 10 marbles. 60% for orange marbles, and 10% for red marbles.

Adding 60% and 10% would be 70%
Subtract 100% (total amount of marbles) and 70% (red and orange marbles).

100% - 70%

Answer 5

30%
