Out of the 10 entrants, there are a total of 5 male and 5 female contestants. We are given that 3 of the men are engineers and 2 of the women are engineers. Therefore, the probability of the winner being a male engineering major is:

(number of male engineering majors) / (total number of contestants)
= 3 / 10
= 0.3

So the answer is B) 0.30.
