Answer:
P=0.05 or 5%
Step-by-step explanation:
The formula to calculate the probability in a continuous uniform distribution is:
Where a is the lower value of the limits of the distribution (a=47.0), b is the upper value of the limit of the distribution (b=57.0), c It is the lowest value in the range from which probability is calculated (c=50.75) and d It is the highest value in the range from which probability is calculated (d=51.25).
7 is half of 14 that's the answer
If the repairman work x hours, then he will charge $35 an hour, so the total of $35*x.
