From the table, the probability of getting exactly 1 girl is 0.018.

The problem is looking for getting 1 or fewer girls, so we should also consider when the number of girls is 0.

The probability of NOT getting a girl is 0.001.

Take the sum of both probabilities.

0.018 + 0.001 = 0.019

The answer is 0.019
