You randomly select one card from a 52 card deck find the probability of selecting a nine or a ten

This is approximately equal to 0.1538

Work Shown:

There are four cards that are labeled "9" and four cards labeled "10"

This is 4+4 = 8 cards we want out of 52 total.

So, 8/52 = (2*4)/(13*4) = 2/13

If you wanted, you can focus on one suit, say the suit of spades. There are two cards we want here: 9 of spades, 10 of spades. There are 13 spade cards total. So this is another way to see why the answer is 2/13.

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
