1 |
Problem |
What is the probability of drawing either a king or a queen in a single draw from a well shuffled pack of 52 cards by using addition theorem. |
|
2 |
Step |
Total number of cards. |
52 |
3 |
Step |
probability of drawing a king card. |
P(A) = \$\frac(4)(52)\$ |
4 |
Step |
probability of drawing a queen card. |
P(B) = \$\frac(4)(52)\$ |
5 |
Formula: |
Addition theorem ⇒ P (A ∪ B) = P (A) + P (B) |
|
6 |
Step |
Simplification. |
\$\frac(4)(52) + \frac(4)(52) \$ |
7 |
Step |
After simplification we get. |
\$\frac(2)(13)\$ |
