Three o cers -- president, treasurer, and secretary -- are to be chosen from among four people: ann, bob, cyd, and dan. bob is not quali ed to be treasurer. cyd's other commitments make it impossible for her to be secretary. dan is irresponsible with money (cannot be treasurer) and might be corrupted by power (cannot be president). how many ways can the o cers be chosen?

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
