Problem |
From a pack of 52 cards, two cards are drawn at random one after the other with replacement. What is the probability that both cards are kings by using multiplication theorem.? |
|
2 |
Step |
probability of drawing the king after replacement. |
P(A) = \$\frac(4)(52)\$ |
3 |
Step |
probability of drawing two kings. |
P(B) = \$\frac(4)(52)\$ |
4 |
Formula: |
Multiplication Theorem ⇒ \$P(A∩B) = P(B) × P(A)\$ |
|
5 |
Step |
Simplification. |
\$\frac(4)(52)\times\frac(4)(52)\$ |
6 |
Step |
After simplification we get. |
\$\frac(1)(169)\$ |
