Lesson Steps
| Step | Type | Explanation | Answer |
|---|---|---|---|
1 |
Problem |
Find a diamond in the first draw and event be getting a red card in the second draw. |
|
2 |
Step |
Probability that the first card is a diamond. |
P(A) = \$\frac(13)(52)\$ |
3 |
Step |
Probability that the second card is a red card. |
P(B / A) = \$\frac(25)(51)\$ |
4 |
Formula: |
Multiplication dependent theorem. \$P(A ∩ B) = P\frac(B)(A) * P(A)\$ |
|
5 |
Step |
Simplification. |
\$\frac(25)(51) \times \frac(13)(52)\$ |
6 |
Step |
After simplification we get. |
\$\frac(25)(204)\$ |
