A Jar has 19 marbles and 5 of them are green you pull 3 marbles without replacement what is the probability that all are green? Write as a fraction
The probability of drawing a green marble on the first try is 5/19.
After drawing one green marble, there are now only 4 green marbles left and a total of 18 marbles left in the jar.
So, the probability of drawing a green marble on the second try is 4/18.
After drawing two green marbles, there are now only 3 green marbles left and a total of 17 marbles left in the jar.
So, the probability of drawing a green marble on the third try is 3/17.
Therefore, the probability of drawing all 3 green marbles is:
(5/19) * (4/18) * (3/17) = 60/581
So, the probability of drawing all 3 green marbles is 60/581 when written as a fraction.
