Answer:
you answer should be b
Step-by-step explanation:
I am not 100% sure
The basic dimensions of any triangle are its area, base, and height.
They're related by the area equation; the area is half of the base times the height, or:

We know the area and the height, so the missing dimension has to be the base. Let's set up an equation by substituting the values the problem gives into the area equation.

Can you solve this equation for

?
Answer: 40% chance
Sample space: 3 white 2 red, 5 pairs
2/5 probability, as a percent would be 40% chance
10% of 4200 is 420
2% of 4200 is 84
420+84 is 504
4200-504=3696
