Part A

Start by drawing a circle of any size you want.
Then cut it in half, and cut it in half again to get 4 equal slices.

P(M) = 1/4
P(A) = 1/4
P(T) = 1/4
P(H) = 1/4
Add up those probabilities to get 1.
1/4 = 0.25 = 25%

The order of the letters does not matter.

--------------------------------------------------

Part B
Start with the previous drawing. Erase the labels.

Then erase the bottom vertical line and the right-most horizontal line

So far we have a 1/4 slice in the upper left corner.
The remaining chunk is 3/4 of the pizza.

Split the 1/4 slice in half to get two copies of 1/8
(1/4)*(1/2) = 1/8

Then be sure to label the appropriate regions.

P(R) = 3/4 = 0.75
P(A) = 1/8 = 0.125
P(T) = 1/8 = 0.125
Add up those probabilities to get 1.
The order of the "A" and "T" does not matter.

Side note: 3/4 = 6/8
