If a single card is drawn from a standard 52-card deck, what is the probability that it is an ace or a spade?
klasskru [66]

A 52-card deck is made up of an equal number of diamonds, hearts, spades, and clubs. Because there are 4 suits, there is a 1/4 chance to draw one of them, in our case, spades.

There are 4 aces in a 52-card deck, so the chance of drawing one is 4/52, or 1/13.

The question asks for the probability of drawing an ace or a spade. Because it uses the word "or," we add the probabilities together. This is because there is a chance of drawing either of the cards; it doesn't have to meet both requirements to satisfy the statement.

However, if the question were to say "and," we would multiply the two probabilities.

Let's add 1/4 and 1/13. First, we can find a common denominator. We can use 52 because both fractions can multiply into it (since the ratio came from a deck of 52 cards as well).

\frac{1}{4} -- > \frac{13}{52}

\frac{1}{13} -- > \frac{4}{52}

Now we can add them together.

\frac{13}{52} + \frac{4}{52} = \frac{13+4}{52} = \frac{17}{52}

This cannot be simplified further, so the probability is 17 in 52, or 33%.

hope this helps!

An architect planned to construct two similar stone pyramid structures in a park. The
kondaur [170]

Answer:

1) Change the length of side AB to 2 feet

Step-by-step explanation:

Given that both structures are similar, it follows that the ratio of their corresponding lengths are equal.

To find out what should be the correct length of AB that she should change to, set up the proportion showing the ratio of 2 corresponding lengths of both structures. Thus:

\frac{PR}{AC} = \frac{PQ}{AB}

We will assume AB is unknown.

PR = 7.5 ft

AC = 2.5 ft

PQ = 6 ft

Plug in the values into the equation

\frac{7.5}{2.5} = \frac{6}{AB}

Cross multiply

AB*7.5 = 6*2.5

AB*7.5 = 15

Divide both sides by 7.5

AB = 2

The architect should change the length of AB to 2 ft

After being hit, the puck travels along the ice at a constant speed. What might cause his motion to change?
Firdavs [7]

Answer:

<em>Hi! Todo here!! UwU</em>

Step-by-step explanation:

Even if the puck is on ice, I wouldn't automatically assume no friction. Otherwise hockey pucks could be tapped slightly and potentially go across entire arenas. I'd say include at least a small friction force opposing motion.
