Pani-rosa [81]

Answer:

7.5

Step-by-step explanation:

<u>To find the median, first order the numbers from least to greatest:</u>

2, 4, 5, 7, 8, 8, 10, 12

<u>Then, find the middle number (number in the middle):</u>

There are 2 middle numbers. 7 and 8.

Because there are 2 numbers, we need to find the average. If there was only one number, that would be the median.

<u>To find the average, add 7 and 8. Then, divide the sum by 2 because there are 2 numbers;</u>

7 + 8 = 15

15 / 2 = 7.5

Have a nice day!

lord [1]

We want to find the probability of randomly drawing a diamond card from a standard deck. We will find that the probability is P = 1/4.

So because we draw a card randomly, every card has the same probability of being drawn. Then the probability of randomly drawing a diamond card is equal to the quotient between the number of diamond cards and the total number of cards.

There are 13 diamond cards and a total of 52 cards, then the probability is:

P = 13/52 = 1/4
