Thwre are 28 clients who don not play any of the instrument using the principle of Venn distribution. 
<u>Using a Venn diagram analogy</u> : 
- Total number of client, U = 108
- Piano, P = 42 
- Guitar, G = 51
- Piano and Guitar, (PnG) = 13 
- None =? 
<u>From the information given</u> :
- P only = 42 - 13 = 29
- G only = 51 - 13 = 38
<u>The total number of clients can be related thus</u> : 
- Total = P only + G only + PnG + None 
108 = 29 + 38 + 13 + None 
108 = 80 + None 
None = 108 - 80
None = 28
Therefore, the number of clients who do not play any of the instruments is 28

Answer:
3.7 hours 
Step-by-step explanation:
Pat could do the job alone in 8 hours. 
Patti could do the job alone in 7 hours
Output = Rate * time
Let the rate at which pat does the work = Rp
Let the rate at which Patti does the work = Rt
Let X be the total output 
Rp * 8 = X
Rp = X/8
Rt * 7 = X
Rt = X/7
If both pat and Patti pick apples, we have
(Rp+Rt)T = X
(X/8 + X/7)T = X
[(7X + 8X)/56]T = X
[X(7+8)/56]T = X
Divide both sides by X
[(7+8)/56]T = 1
(15/56)T = 1
T = 56/15
T = 3.7 hours
