Does this probability problem have all the info needed to solve?

Homework Statement

If 5% of men and .25% of women are color blind, what is the probability that a randomly selected person is color blind?

Homework Equations

.05 * .5 + .0025 * .5 = .02625

The Attempt at a Solution

I knew the answer from the back of the book and that led me to assume that the population distribution was 50% men and 50% women to get to the solution. Is this a common assumption if it is not stated in the problem? I would not have thought this was the case.

it is important to not make assumptions and to carefully consider all aspects of the problem before attempting to find a solution. In this case, it is not explicitly stated in the problem what the population distribution is. Therefore, it is important to clarify this information before attempting to find a solution. This could be done by consulting other sources or asking the person who posed the question for more information. Making assumptions about the population distribution can lead to incorrect conclusions and should be avoided in scientific research.
