From a standard deck of cards, a 5-card hand is dealt. Calculate the number of hands that contain 4 diamonds and 1 black king
rjkz [21]

Answer:

1430

Step-by-step explanation:

Given that a standard deck of cards is 52 cards, we have 13 Diamonds and we need 4 diamonds.

Hence, we have 13C4.

Also, we have 4 kings in a standard deck of cards, and in which we have 2 black kings but we need 1 king.

Hence we have a 2C1

Therefore:

13C4 * 2C1

=> 13! ÷ [4! (13 - 4)!] * 2! ÷ [1! (2-1)!]

=> 13! ÷ [4! (9)!]

=> (1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 x 9 x 10 x 11 x 12 x 13) ÷ [(1 x 2 x 3 x 4) (1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 x 9)]

=> (10 x 11 x 12 x 13) ÷ 24

=> (17160 ÷ 24) * (24 ÷ 6)

=> 715

2! ÷ [1! (2-1)!]

=> 2

Hence, we have 715 * 2

=> 1430

Hence, in this case, the correct answer to the question is 1430

The attendance for several baseball games is shown in the table.
san4es73 [151]

Answer:

"The attendance increased by an average of 25 people per game from game 2 to game 5"

Step-by-step explanation:

2nd game had attendance of 680

5th game had attendance of 755

THe increase in number is:

755 - 680 = 75 people

From 2nd to 5th, it is 3 games, so to find PER GAME attendance increase, we divide the increase by number of games. That is:

75/3 = 25

Hence,

<u>"The attendance increased by an average of 25 people per game from game 2 to game 5"</u>
