Answer 1

Jake found that 39 students in his school could play the guitar and 17 of those students could play the piano
Can play guitar and piano-=17      ---->top left
Can play guital total= 39              ------> top right
Which mean
Can play guitar but cant play piano= 39-17=22 ------> top middle

There were 8 students who could not play the guitar but knew how to play the piano.
Can play piano but can't play guitar= 8 ---->middle left
Can play piano total= 8 + 17= 25             ----->bottom left

There were 3 students who knew neither guitar nor piano
Did not know the guitar and piano=3          ----->middle middle

The answer would be: 
Knew piano Did not know piano Total
Knew guitar 17 22 39
Did not know guitar 8 3 11
Total 25 25 50

Answer 2

Answer:

                                 knew piano              did not know piano        total

knew guitar                    17                                  22                               39

didnot know guitar          8                                    3                                11

total                                25                                    25                             50

step by step solution:

• Jake found that 39 students in his school could play the guitar and 17 of those students could play the piano, as well.

• There were 8 students who could not play the guitar but knew how to play the piano.

• There were 3 students who knew neither guitar nor piano.

Hence the total number of people who knew to play guitar is:

39

and those who do not know how to play guitar is: 8+3=11

The total number of people who knew to play piano is: 17+8=25

and the total number of people who do not know to play piano =(39-17)+3=22+3=25.

The table of the following information could be given as:

                                 knew piano              did not know piano        total

knew guitar                    17                                  22                               39

didnot know guitar          8                                    3                                11

total                                25                                    25                             50
