Answer:
In B, One card is chosen from a standard deck, it is set aside, then a second card is drawn. That "set aside" is where we have a problem. We began with 52 cards, but now have 51. This fact WILL change the probability or probabilities. Chances of obtaining a red heart from the full 52-card deck are 4/52; whereas chances of obtaining a red heart from the remaining 51 cards (assuming that you got a red heart earlier and set it aside) is 3/51.

Step-by-step explanation:
<h2><u>Mean and Median</u></h2>
<h3>solve for the mean and median of the following data: 20, 10, 15, 18, 12, 17</h3>
<h3><u>Mean</u></h3>
To find the mean of a data set, use the formula:
<u>mean</u> = <u>sum of the data points</u>/<u>number of the data points</u>
We will determine the sum of the data points.
- 20 + 10 + 15 + 18 + 12 + 17 = 92
Since the number of data points is 6, we will divide the sum and the number of data points as shown in the formula above.
<u>Answer:</u>
- The mean of the data set is <u>15.3</u>.
<h3><u>Median</u></h3>
To find the median of the data set, arrange the data set into ascending order and the value in the middle is the median. The median should be an even number.
- 20, 10, 15, 18, 12, 17
- 10, 12, 15, 17, 18, 20
The middle value is 15 and 17. Find out their sum and divide it into 2.
<u>Answer:</u>
- The median of the data set is <u>16</u>.
