Step Type Explanation Answer

1

Problem

Two cards are selected without replacing the first card from the deck. Find the probability of selecting a king and then selecting a queen by using multiplication theorem?

2

Step

Probability of selecting a king.

P(A) = \$\frac(4)(52)\$

3

Step

probability of selecting a queen.

P(B) = \$\frac(4)(51)\$

4

Step

total number of events.

52

5

Formula:

Multiplication Theorem ⇒ \$P(A∩B) = P(B) × P(A)\$

6

Step

Simplification.

\$\frac(4)(52)\times\frac(4)(51)\$= \$\frac(16)(2652)\$

7

Step

After simplification we get.

\$\frac(1)(166)\$
