Answer: 
a) 40 hours
b) 60 hours
C) 100 hours
Step-by-step explanation:
0.2a + 0.3b+0.5c = 76
Hence: 0.2* (0.2 λ) +0.3*(0.3 λ )+0.5*(0.5 λ ) = 76
0.38 λ =76
 λ = 76/0.38 =200
Thus : 40, 60, 100
 
        
             
        
        
        
Answer:
b.  70
Step-by-step explanation:
The Binomial Coefficient can be used to calculate the number of ways objects can be arranged.  
<u>Binomial Coefficient</u>

The exclamation mark "!" placed after a number means factorial and indicates to multiply all whole numbers from the given number down to 1.
Example:  4! = 4 × 3 × 2 × 1
The Binomial Coefficient gives us the number of ways of picking "r" unordered outcomes from "n" possibilities.
As there are 8 friends  ⇒  n = 8.
As each car takes 4 friends  ⇒  r = 4.
Substitute these values into the formula:
