An urn contains 13 red balls and 7 blue balls. Suppose that three balls are taken from the urn, one at a time and without replac

d1i1m1o1n [39]

Answer:

0.749

Step-by-step explanation:

The probability that at least one of the three taken balls is blue is the inverse of the probability that none of the three taken balls is blue, aka all 3 of the taken balls are red. The probability of this to happen is

In the first pick: 13/20 chance of this happens

In the 2nd pick: 12/19 chance of this happens

In the 3rd pick: 11/18 chance of this happens

So the probability of picking up all 3 red balls is

$\frac{13*12*11}{20*19*18} = \frac{1716}{6840} = 0.251$

So the probability of picking up at least 1 blue ball is

1 - 0.251 = 0.749
