the probability of getting a black one given that in the first draw we got a black one is P = 1/2 = 0.5
<h3>
How to find the probability?</h3>
We will assume that all the beads have the same probability of being randomly selected.
Then the probability of picking a black bead is equal to the quotient between the number of black beads and the total number of beads.
Originally, there are 4 black ones and 3 red ones ( a total of 7).
We want to get the probability of getting a black one given that in the first draw we got a black one.
If in the first draw we got a black one, then now there are 3 blacks and 3 reds (a total of 6 beads).
So the probability of getting another black one is:
P = 3/6 = 1/2 = 0.5

Step-by-step explanation:
673.97 in² is the answer
So the total area is= square + semicircle
Area of square= 22²= 484in²
Area of semicircle= 1/2(πr²)
diameter of semicircle is 22 so the radius is 11 in
the area = 1/2(3.14*121)
area= 189.97
The total area= 189.97+ 484= 673.97in²
