Suppose James randomly draws a card from a standard deck of 52 cards. He then places it back into the deck and draws a second ca
shutvik [7]

Answer:

0.01923 or 1.92 %

Step-by-step explanation:

The probability of drawing a queen card out of deck is 4/52

∴ P(Q)= 4/52

there are 4 queens in a deck, one of each suit.

The probability of drawing a diamond card out of deck is 13/52

∴P(D)= 13/52

there are 13 cards in diamond suit (including the three face cards).

The total will remain 52 as he has replaced the first card and have not moved it aside

therefore, the net probability for both scenarios will be defined by calculating both probabilities.

P= P(Q) x P(D)

P=  4/52 x 13/52

P=1/52

P=0.01923 (converting into percentage)

P=0.01923  x 100%

P=1.92 %

Answer: the probability that James draws a queen card as the first card and a diamond card as the second card is 1.92%

A seed company planted a floral mosaic of a national flag. The perimeter of the flag is 2 comma 400 ft Determine the​ flag's wid
Westkost [7]

Answer:

the width is 470 ft and the length is 730 ft.

Step-by-step explanation:

Perimeter of a flag is 2l+2w

Let w = width

Let l = w+260

2(w+260)+2w=2,400

2w+520+2w=2400

4w+520=2400

4w=1880

w=470

So, the length would be 470+260, or 730

Therefore, the width is 470 ft and the length is 730 ft.

I hope this helped and have a good rest of your day!
