To select two students to read the morning announcements, the principal places 5 girls names and 4 boys names in a bag. what is the probability that both students selected to read the morning announcements will be 2 girls?

First let's measure how many ways can be the announcement done.

We have 9 people. So 9 options for first person and 8 option for the second.We get 72 possibilities. Since it doesn't matter a is with b or b is with a the possibilities go down to 36.

Now let's count how many ways we can make 2-girl pair

we can 5 options for the first person and 4 options for second. The same way divide this by 2 we are left with 10 possibilities.

So we got that there are 36 pairs possible.

At least find the probability divide the wanted outcome by the possible numbers of outcomes. 10/36=5/18

Answer 5/18

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

irrational, cannot
