The probability of having a baby with a vascular birthmark is 1 in 10, which can also be expressed as a probability of 0.1 (1/10). The probability of having a boy is 0.5 (assuming an equal probability of having a boy or girl). To calculate the probability of having a boy with a vascular birthmark, we multiply the probability of having a boy (0.5) by the probability of having a vascular birthmark (0.1), which gives us 0.05 (or 5%). Therefore, the best choice is C) 5%.
