Explanation: Hello Students, time to practice and review the steps for the problem. |
Lesson Steps
| Step | Type | Explanation | Answer |
|---|---|---|---|
1 |
Problem |
Find the probability that the second ball is black and the first one is white. |
|
2 |
Step |
A and B are dependent events. |
|
3 |
Step |
probability of selecting the white ball first. |
P(A) = \$\frac(18)(27) = \frac(2)(3)\$ |
4 |
Step |
probability that a white ball has been taken out of the bag. |
P \$\frac(B)(A) = \frac(9)(26)\$ |
5 |
Formula: |
Multiplication dependent theorem. \$P(A ∩ B) = P(B / A) * P(A)\$ |
|
6 |
Step |
Simplification. |
\$\frac(9)(26)\times\frac(2)(3)\$ |
7 |
Step |
After simplification we get. |
\$\frac(3)(13)\$ |
