Answer:

The probability of being all females is 60%.

The probability of being all males is 40%.

We know that 40% of the population is male.

If someone selected 9 students, the probability of being all males is 40%. But, the probability of being all females is 60%, because there are only two genders and females represents the complete set of the given probability.
