You only need to consider the situations where 10 or 11 of the babies are girls, then subtract those probabilities from 1. This will give probability that any other number up to 9 of the babies are girls.
Use binomial theorem.

n = 11
k = 10,11
p = 1/2

Hey there!
<h3>Guide: </h3>
- Negative & negative = positive
- Positive & negative = negative
- Positive & positive = positive
- Negative & positive = negative
<h3>So, far <u>in your particular question we’re doing</u> <u>positive</u> (7) <u>&</u> <u>negative</u> (-2) so <u>that means your</u> <u>result will most likely be a negative </u></h3><h3 />
<em>Now let’s answer your question, shall we </em>
<h2>7 • (-2) =
<em><u> -14</u></em> </h2>
Good luck on your assignment and enjoy your day!

Draw the shape by drawing dots at the co-ordinates.
Connect them in order, so if it's KLMN, connect K to L then to M then N.
Then, pick one of the points, I'd choose K, then move that dot 3 to the right, then move it 4 up. Do the same for all of the letters.
Method OneYour calculator might be able to do this. Mine does it like this.
6
nCr
2
=
15
Method 2You could simply set up 6C2
This gives you
Method ThreeYou only have to do this a couple of times to see how the cancellation works.

After all the cancellation takes place you have
6*5/2 = 15
