Answer:

there are twelve total combinations

Step-by-step explanation:

just by looking at the problem though,

ABCD

normally, because some of them are repeated, we need to get rid of some

since this is about passwords though, we need to keep all of the same twelve combinations because the order of the letters are important

2 cards are chosen from a deck of cards. The first card is replaced before choosing the second card. What is the probability tha

fgiga [73]

Answer:

The probability that the first card chosen is club and second card chosen is of heart is .

Step-by-step explanation:

Total number of cards in the deck is 52 (total number of cases).

Probability of an event E can be formulated as:

$P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}$

For event A, number of cards of type club = 13 (favorable cases)

So,

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

For event B, number of cards of type heart = 13 (favorable cases)

So,

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

It is given that card is replaced before choosing the second card.

These events A and B are independent events, happening of one event does not effect the happening of other. And probability of both happening together can be found as following:

$P(A \cap B) = P(A) \times P(B)$

$\Rightarrow P(A \cap B) = \dfrac{1}{4} \times \dfrac{1}{4}\\\Rightarrow P(A \cap B) = \dfrac{1}{16}$

The probability that the first card chosen is club and second card chosen is of heart is $\frac{1}{16}$ .
