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

step-by-step explanation:

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
