I NEED HELP ASAP PLEASE SOMEONE HELP ;(

See below.

Step-by-step explanation:

This is what the table has:

Gender       Biology      Chemistry       Physics      Total

Girl                   42               39                   23           104

Boy                                      45                   32

Total

The total number of students is 200.

There are 104 girls. 200 - 104 = 96. There are 96 boys.

Also add all students who chose Chemistry: 39 + 45 = 84

Add all students who chose Physics: 23 + 32 = 55

Now we have this:

Gender       Biology      Chemistry       Physics      Total

Girl                   42               39                   23           104

Boy                                      45                   32           96

Total                                   84                    55           200

Add 45 and 32 and subtract from 96 to get boys who chose Biology.

96 - (45 + 32) = 96 - 77 = 19

Now add 42 and 19 to find the total of Biology.

42 + 19 = 61

The full table is below. The filled in numbers are in bold face.

Gender       Biology      Chemistry       Physics      Total

Girl                   42               39                   23           104

Boy                   19               45                   32           96

Total                 61               84                    55           200

560
