(2/7)m - (1/7) = 3/14
2m/7 =(3/14) + (1/7)
2m/7 = (3/14) + 2(1/7)
here we are multiplying 2 with 1/7 to make the denominator same for addition.
2m/7 = (3/14) +(2/14)
2m/7 = (3 + 2)/14
2m/7 = 5/14
2m = (5 *7)/14
2m = 35/14
2m = 5/2
m = 5/4
m = 1.25
So the value of "m" is 1.25
It’s 58 because the length is increasing by 14
It would be 600 + 50 + 8 + 0.1 + 0.02 + 0.009
Answer: 0.0898
Step-by-step explanation:
Probability = 
Given : Sample size : 528
Number pf customers say they are happy = 237
Probability of getting one happy customer= 
Probability of getting second happy customer=
[subtract 1 from both numbers]
Probability of getting third happy customer=
If 3 customers are elected without replacement
The probability they will all say they are happy with the service =

Hence, the required probability = 0.0898
