Answer:

a. 3/13 or 23.08%

b. 1/13 or 7.69%

c. 1/4 or 25.00%

d. 1/52 or 1.92%

Step-by-step explanation:

Number of cards in a deck = 52

a. A face card

Considering there are four suits and each suit has three different face cards, the probability that the card is a cafe card is:

P_{F} =\frac{3*4}{52}\\ P_{F} =\frac{3}{13}

b. A queen

There are 4 queens in the deck, on of each suit, thus the probability of getting a queen is:

P_{Q} =\frac{4}{52}\\ P_{Q} =\frac{1}{13}

c. A spade

There are four suits with the same number of cards in a deck, therefore, the probability of getting a spade is:

P_{S} =\frac{1}{4}

d. A jack of spades

Since there are no repeated cards, there is only one jack of spades in a 52 cards deck:

P_{J+S} =\frac{1}{52}

There will be two squares.

Think about it: The shorter side is 3.5 feet. The longer side is 7 feet. If he cuts it in half on the longer side, he's taking the length of that longer side, and dividing it by 2. 7/2=3.5.

So, you'd have two squares, both with a length and width of 3.5 feet.

Rewrite this non-statistical question as a statistical question. How many minutes do I exercise each day?
stira [4]

Answer:

The statistical question should be

"how many minutes do I exercise on each day of the week" and "how many minutes do I exercise each day of the week whilst there is background music"

Step-by-step explanation:

Here we have the non statistical question, how many minutes do I exercise each day

We note that a statistical question is one in which there are are different variety answers, where the distribution and the inclination of the the answers is sought

Therefore, statistically, we should ask, "how many minutes do I exercise on each day of the week" or "how many minutes do I exercise each day of the week whilst there is background music".
