At a particular bank, 57% of the loans are written by Miss Jones, 40% by Miss Alvarez, and 21% by both officers working together. If one loan is selected at random from this bank, find the probability that it was written by: Jones or Alvarez

the loan written by Mrs Jones alone is 57%-21% = 36%, by Miss Alvarez alone is 40%-21% = 19%, 

thus the probability is 36%+19%+21% = 76%
