Answer;
0.3430
Solution and explanation;
Probability of a product being acceptable is 70% or 0.7
Probability of the product being defective is 30 % or 0.3
Therefore; If three of the products are randomly selected, the probability that all of them are acceptable will be;
= 0.7 × 0.7 ×0.7 or 0.7 ³ = 0.3430
= 0.3430 .
