You are a chief for an electric utility company. The employees in your section cut down trees, climb poles, and splice wire. You report that of the 128 employees in your department 10 cannot do any of the three (management trainees), 25 can cut trees and climb poles only, 31 can cut trees and splice wire, but not climb poles, 18 can do all three, 4 can cut trees only, 3 can splice wire, but cannot cut trees or climb poles, and 9 can do exactly one of the three. How many employees can do at least two of the three jobs mentioned?

109 Employees

Step-by-step explanation:

Total Number of Employees, Universal Set=128

Key: P=Climb poles, T=Cut down trees, W=Splice wire

Since 9 can do exactly one of the three.

Number of Employees who can do at least two of the jobs

109 Employees can do at least two of the jobs.

OR

Therefore: Number who can do at least two jobs

=128-(10+9)=109

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
