Question

There are 6 blue marbles,7 black marbles,4 orange marbles,and 3 green marbles in a bag. Once a marble is drawn,it is REPLACED. Find the probability of the outcome

heres the question
a blue marble,an orange marble,and then a green marble
a)0
b)9/1000
c)6/35
d)3/500

Answer 1

Blue is 6 out of the 20 marbles
Orange is 4 out of the 20 marbles
Green is 3 out of the 20 marbles

Probability is 6/20 * 4/20 * 3/20
I would reduce the 6/20 to 3/10 and the 4/20 to 1/5 so
Probability = 3/10 * 1/5 * 3/20 = 9/1000

So you would get a blue then an orange then a green approximately 9 out of every 1000 tries.
