A quality check manager designs a simulation using a random generator, where numbers 0, 1, 2, and 3 represent that a bulb works correctly, and the number 4 represents that a bulb is defective. The quality check manager performs the simulation 20 times. The table shows the results. 112 441 200 421 334
032 012 230 103 120
201 244 102 022 032
343 010 443 004 344

Based on the results of the simulation, what is the probability that the next 3 bulbs will all work correctly? (HOW DID YOU GET YOUR ANSWER PLEASE SHOW ME YOUR WORK!!)

A. 15

B. 25

C. 35

D. 45

Ok hold on one moment

Step-by-step explanation:

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3

practice. practice. practice.
