Lesson Steps
| Step | Type | Explanation | Answer |
|---|---|---|---|
1 |
Problem |
Find the probability that he chooses 2 red balls. |
|
2 |
Step |
Probability of selecting the red ball on first attempt. |
P(A) = \$\frac(4)(7)\$ |
3 |
Step |
Probability of selecting the red ball on second attempt. |
P(B / A) = \$\frac(3)(7)\$ |
4 |
Formula: |
Multiplication dependent theorem. \$P(A ∩ B) = P\frac(B)(A) \times P(A)\$ |
|
5 |
Step |
Simplification. |
\$\frac(4)(7) \times \frac(3) (7)\$ |
6 |
Step |
After simplification we get. |
