Answer:
0.38% probability that the sample contains exactly two defective parts.
Step-by-step explanation:
For each part, there are only two possible outcomes. Either it is defective, or it is not. The probabilities for each part being defective are independent from each other. So we use the binomial probability distribution to solve this problem.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
In this problem we have that:
What is the probability that the sample contains exactly two defective parts?
This is
0.38% probability that the sample contains exactly two defective parts.

small=12*8*4=384
large=20*15*9=2700
space=large-small
space=2700-384

Estimated bill amount is $57
Step-by-step explanation:
Round off the cost of 1 appetizer.
Cost of 1 appetizer = $6.50 ≈ $7
Find the cost of 2 main courses.
Cost of 1 main course = $15.75 ≈ $16
∴ Cost of 2 main courses = 2 × 16 = $32
Find cost of 2 drinks.
Cost of 1 drink = $2.25 ≈ $2
∴ Cost of 2 drinks = 2 × 2 = $4
Find the cost of 2 desserts.
Cost of 1 dessert = $7.25 ≈ $7
∴ Cost of 2 desserts = 7 × 2 = $14
Add all and find the total cost.
Estimated Total bill amount = 7 + 32 + 4 + 14 = $57
