Alocal factory uses a manufacturing process in which 70% of the final products meet quality standards and 30% are found to be defective. if three of the products are randomly selected, find the probability that all of them are acceptable. 0.343 0.027 0.429 2.1

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 .

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

i think it would be 42cm
