Question:

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?

Answers

Answer: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 pairwe 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=5/18Answer 5/18
