5% of all widgets are defective. there is a 30% chance that a widget was produced at the foo factory. if a widget was produced a
VARVARA [1.3K]
A.) P(defective | foo) = P(defective & foo)/P(foo)
  4% = P(defective & foo)/30% . . . . . . . . . plug in the given data
  0.04*0.30 = P(defective & foo) = 0.012 = 1.2%

The probability that a widget was produced at the foo factory and is defective is 1.2%.

b.) P(defective | foo) ≠ P(defective) (4% ≠ 5%), so the events P(defective) and P(foo) are NOT independent.

c.) P(foo | defective) = P(defective & foo)/P(defective)
  P(foo | defective) = 1.2%/5% = 24%

The probability that a widget was produced at the foo factory given it is defective is 24%.

N(n+p)-n; use n=5, and p=3​
andrew-mc [135]

Answer:

45

Step-by-step explanation:

We can first expand the expression:

n(n+p) - n

= n^2 + np + n

Then, we can plug in values of n and p into the expression:

n^2 + np + n = (5)^2 + (5)(3) + 5 = 25 + 15 + 5 = 45
