probability they are all males is 0.041

<u>Step-by-step explanation:</u>

Here we have , 55% of college freshmen are women. If you pick 4 freshmen at random . We need to find What's the probability they are all males . Let's find out:

Probability to have women is 55 % i.e. 0.55 so for men is :

⇒ $1-0.55$

⇒ $0.45$

Now , 4 persons are randomly chosen and we need to find probability to have all 4 males that will be :

⇒ $0.45(0.45)(0.45)(0.45)$

⇒ $0.45^4$

⇒ $0.041$

Therefore , probability they are all males is 0.041

Answer:

Edit: This is incorrect, it might actually be the 3rd answer, draw arcs on either side of a given point on the line?

Draw arcs on either side of a given point off of the line I believe.

Step-by-step explanation:

Bisect a Segment:

Step 1 - open up your compass so that it is slightly larger than the segment. Put the compass on point A on the given segment and swing an arc above and below the lines. Do the same on point B. Create the points where the circle intersects.

Step 2 - Draw a line going through the points. That’s the bisector.
