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.

anyone???

abdullahm · Answer

There are only 3 marble colors - red, yellow and orange

michele_laino · Answer

Hint:
the sum of your probabilities has to be equal to 1

abdullahm · Answer

So, to find out how much for orange we have to do 100% - probability for both red and yellow

thesmartone · Answer

Or, if you want to simplify the percents to decimal, you can do as Michele said :)

Okay i think i got it thanks guysss c:

michele_laino · Answer

hint:
we have top solve this equation:
$$x + 60 + 10 = 100$$
where x is the requested probability

oops..we have to solve...

anonymous · Answer

if the total marbles(10) = 100%, then 1% = 10/100 = 0.1 
and 10% are red marbles = 10 x 0.1
 and 60% are yellow= 60 x 0.1
then that leaves 30% for the yellow marbles

anonymous · Answer

sorry for the orange marbles (30%)

anonymous · Answer

P(red marble) = 1/10 x 100 = 10%
P(yellow marble) = 6/10 x100 = 60%
P(orange marble)= 3/10 x100 = 30%
