0.84 = 84% probability that the calculator has a good case and good batteries.
Step-by-step explanation:
We have these following percentages:
8% of a certain batch of calculators have a defective case.
11 % have defective batteries.
3% have both a defective case and defective batteries.
Using Venn Diagrams:
Event A: Defective Case
Event B: Defecitve Battery
So the probabilities are:
Probability of at least one problem:
Find the probability that the calculator has a good case and good batteries.
No problems, so
0.84 = 84% probability that the calculator has a good case and good batteries.
