Hi,
Yes, total sample is 1000 of which 600 are female
P(female) = 600/1000 Or 3/5
Yes, total sample is 1000 of which 200 have red hair
P(red hair)= 200/1000 Or 1/5
Assuming I am understanding your question properly
We are looking for the probability of picking either a female 'or' a red head.
P(female 'or' a red head) = 3/5 + 1/5 = 4/5
