Since you are given that the student registered early, the total number you deal with is all students who registered early.
211 + 329 = 540
number of undergraduates who registered early = 211
Among students who registered early:
p(undergraduate) = 211/540
The answer is 165. If you add 33 five times you get 165. Or you could do what i did and do 33 times 5.
It would be .12 because 27/75 would equal 3/25 the you could just change to a decimal.
You multiply 26 x 50 that equals 1,300
If the number after 3 is 1 then the answer is 48j-132
