Answer:

Step-by-step explanation:

In a standard deck of cards, there 54 cards (52 cards plus 2 Jokers). There are 4 suits (kinds of shapes) in a deck namely: Clubs, Diamonds, Hearts and Spades. Each of the suits numbers from number 2 to number 10 (numbering 36 cards). Afterwards, we have 4 suits each for the Jack, Queen, King & Ace cards (numbering 16 cards). And then 2 Jokers

An Ace turned up at the 20th card, this means there 34 cards left. The number of cards left is given by the difference between 54 & 20. Mathematically shown below:

Cards left = 54 - 20 = 34

Total number of cards = 54, number of Aces of Spades ♠ in the deck = 1, number of two clubs ♣ in the deck = 1

A. Probability of the next card being Ace of Spades ♠ = the number of Ace of Spades card in the deck ÷ Total number of cards left in the deck

Pr (Ace of Spades) = 1 ÷ 34

Pr (Ace of Spades) = 0.0294 or 2.94%

B. Probability of the next card being Two of Clubs ♣ = the number of Two of Clubs card in the deck ÷ Total number of cards left in the deck

Pr (Two of Clubs) = 1 ÷ 34

Pr (Two of Clubs) = 0.0294 or 2.94%

It therefore implies that the chancess of the next card being Ace of Spades (A ♠) or Two of Clubs (2 ♣) is the same; the Ace of Spades is just equally as likely to be picked as the next card from the deck as Two of Clubs

El garage "Bolivar" tiene3 pisos. En el primero hay 5 filas con 20 lugares en cada una. En el segundo y en el tercero, 4 filas c
Iteru [2.4K]

Answer:

220 automóviles

Step-by-step explanation:

Aquí, queremos saber la cantidad de autos que ingresarán al garaje cuando esté completamente ocupado.

De la pregunta, nos dicen que hay 3 pisos. Para el 1er piso, hay 5 filas de 20 lugares.

El número total de autos que pueden estar en esto será 5 * 20 = 100 autos.

Para el segundo y tercer piso, tenemos 4 filas de 15 cada una.

El número total de autos aquí será 2 (15 * 4) = 2 * 60 = 120 autos

El número total de automóviles cuando está completamente ocupado es, por tanto, = 100 + 120 = 220 automóviles

Please help with at least one question.
Cloud [144]
Okay, first off negative is well negative and since there is no other negatives, -5/7 is least (making it go first). Second, what is smaller 3/5 or 2/9, remember that the bigger the denominator the smaller the piece.

[/] [/] [/] [] [] = 3/5

[/] [/] [] [] [] [] [] [] [] 2/9

At the end it should be -5/7, 2/9 , 3/5. This method can go the same for problems like these...Hope it helps!
