A flower shop has 11 red roses, 7 pink roses, 9 white roses, and 3 yellow roses in stock. One type of rose is randomly selected for a flower arrangement. What is the probability that the selected rose is red or yellow?

in simplist form: 1/10

Step-by-step explanation:

11 plus 7 plus 9 plus 3 gives you 30 in total, compared to 3 yellow

when you compare you get 3/30

simplify and get 1/10

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
