    This week's question:
    What are the four types of evidence that Darwin used to support his concept of evolution?
    Last week's question:
    Colorblindness is present in 1 out of every 10 males and 1 out of every 100 females in the United States. Suppose a group of 10,000 people is 60% female.  How many males and females in that group would be likely to be colorblind?

    It is likely that 460 people in the group would be colorblind (400 males and 60 females).
