Lesson Steps
| Step | Type | Explanation | Answer |
|---|---|---|---|
1 |
Problem |
what is the probability they also bought a Monitor |
|
2 |
Step |
Probability of CPU buyers |
P(A) = 40% = 0.4 |
3 |
Step |
Probability of monitors buyers |
P(B) = 30% = 0.3 |
4 |
Step |
Probability of intersection of CPU and monitors |
P(A∩B) = 20% or 0.2 |
5 |
Formula: |
Conditional probability \$P(B/A) = (P(A∩B)) / (P(B))\$ |
|
6 |
Step |
Simplification |
\$\frac(0.2)(0.4) = \frac(2)(4)\$ |
7 |
Step |
After simplification according to formula |
\$\frac(1)(2)\$ |
