PLEASE HELP !!! I need this answer with an explanation.

Part A

Answer: 50

--------------------

Explanation:

Circle the "male" row and the "sports" column. The value 0.25 is in this row/column intersection

Multiply 0.25 by the value 200, since there are 200 people total, to get
0.25*200 = 50

============================================================

Part B

Answer: 50

--------------------

Explanation:

Add up the values in the "reading" column to get 0.10+0.15 = 0.25

Then like before, we multiply 0.25 with 200 to get 0.25*200 = 50

The same amount of people prefer reading compared to the number of men who like sports.

============================================================

Part C

Answer: 70

--------------------

Explanation:

Add up the values along the "female" row
0.15+0.05+0.15 = 0.35

Multiply this with 200
0.35*200 = 70
