Answer 2

Answer:

0.0625 = 6.25% probability that the first card drawn is a diamond and the second card is a club

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Probability of independent events:

The probability of independent events happening at the same time is the multiplication of the probabilities of each events.

First card:

A standard deck has 52 cards, of which 13 are diamonds. So

$P(A) = \frac{13}{52} = \frac{1}{4}$

Second card:

The first card is replaced, so still 52 cards, of which 13 are clubs. So

$P(B) = \frac{13}{52} = \frac{1}{4}$

What is the probability that the first card drawn is a diamond and the second card is a club?

Each drawing is independent, so

$P(A \cap B) = P(A)*P(B) = \frac{1}{4}*\frac{1}{4} = \frac{1}{16} = 0.0625$

0.0625 = 6.25% probability that the first card drawn is a diamond and the second card is a club
