Answer 3

the area of those 2 triangles

Answer 4

the area under the curve is the probaility, all the area in that graph is equal to 1, as the probability of everything has to add up to 1,

so you can also just take 1 and subtract the area of that square in between that is not being used and stilll get the area of everything left

or you can find the area of each triangle
