Answer:

see below

Explanation:

P( math or english) = number of math or english / total

This would include the people that studied both (20+11+39)

= 70/100

P( math and english) = number of math and english / total

This is the people that studied both

= 11/100

P( math or english but not both) = number of math or english / total

This includes only the people that study one or the other but not both (20+39)

= 59/100
