The theoretical probability that a man will have some form of color blindness is 8%, whereas the theoretical probability of a woman having color blindness is 0.5%. If you have a group of 600 women, predict how many of them will be color blind.
3 women. What I do is if the overall number is a multiple of 100, I just start from 100 because 100=100%. So 1=1%. So then multiply it by 6. So 1% of 600 would be 6. Then 6÷2 is 3. That's your answer. .5%=3
