Gustavo tested 1000 calculators to see if any were defective. the company claimed that the probability of a defective calculator was 1% per 1000 calculators. gustavo found 15 defective calculators out of 1000. what was the predicted frequency? predicted frequency . . =(# of trials)(theoretical probability) =(1000)(0.01) the predicted frequency was a: 1b: 10c: 100d: 1000 what was the relative frequency? relative frequency = observed frequency/total number of trails the relative frequency was a: 0.15%b: 1%c: 1.5%  d: 15%
