The mean is all the numbers added together then divided by the amount of numbers there were.
Ex~1,2,3,4,5
Add them all together: 15
Divide by 5 because there is five numbers 15/5=3
The median is the middle number once you put then in order from smallest to largest (or the other way around).
Ex~ 3,5,2,4,1
Rearrange: 1,2,3,4,5
Find the Middle: 3
The median is 3 because it is in the middle of them all once you put them in smallest to largest.
Hope this helped

Answer:
So the best option is c) 0.1912
Step-by-step explanation:
For this case we have a standard deck of 52 cards and we consider the experiment without replacement.
So then we have 13 heart cards and 52-13 = 39 NOT heart cards
In order to find the probability that we select a heart card in the first extraction we have this:
Now for the second extraction we have a total of 51 cards since we select one at the first extraction and we can find the probability of not heart like this:
And for this case we can assume that we have independent events since the extraction of the first and second card are not related events and assuming this we have this probability:
So the best option is c) 0.1912
