You are right with multiplying 100 and 3. An easier way to do it is to divide 300 and 4, so you can get the blank.
Assuming that (-3x + 4) and (2x + 7) are two legs of a rectangle, you can find the perimeter like this: P = 2*length + 2*width.
P = 2*(-3x + 4) + 2*(2x + 7)
P = -6x + 8 + 4x + 14
P = -2x + 22

Hello!
First you have to find the probability of them happening separately
To find this you do the amount of favorable outcomes over the total amount of outcomes
Joey is only 1 kid and there are 12 total
This is a chance of 1/12
Chloe is 1 kid out of 11 now since Joey was already picked
This is a chance of 1/11
Zoe is 1 kid out of 10 since Joey and Chloe was already picked
This is a chance of 1/10
To find the probability of them happening separately you multiply them together
1/12 * 1/11 * 1/10 = 1/1320
The answer is C) 1/1320
Hope this helps!
