if three balls are drawn at random, what is the probability that at least one of them is blue?

Step 1

Three balls are randomly drawn from the box.

The probability of at least one of them is blue can be calculated as follows.

Step 2

From the three balls, the probability of getting one ball as blue is 1/3.

The probability of getting two balls as blue is 2/3.

The probability of getting all the 3 balls as blue is 3/3, which is 1.

Step 3

The probability of getting at least...
