So we know that 3 muffins mean 36 batches right?
We need to find out how much muffins are there in one batch.
To do that we must divide 36 by 3 which gives us 12.
Now we know that there are 12 muffins in one batch.
So four batches means 4 multiplied by 12 which gives us 48.
So there are 48 muffins in 4 batches

Answer:

0.5015 = 50.15% probability that it came from manufacturer A.

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

In which

P(B|A) is the probability of event B happening, given that A happened.

$P(A \cap B)$ is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Defective

Event B: From manufacturer A.

Probability a unit is defective:

2% of 43%(from manufacturer A)

1.5% of 57%(from manufacturer B). So

$P(A) = 0.02*0.43 + 0.015*0.57 = 0.01715$

Probability a unit is defective and from manufacturer A:

2% of 43%. So

$P(A \cap B) = 0.02*0.43 = 0.0086$

What is the probability that it came from manufacturer A?

$P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.0086}{0.01715} = 0.5015$

0.5015 = 50.15% probability that it came from manufacturer A.

Answer:

c=3

Step-by-step explanation:

4c+12-2c=5c-3 1. combine like terms

2c+12=5c-3 2. -5c on both sides

-3c+12=3 3. -12 on both sides

-3c=-9 4. /-3 on both sides

c=3
