Answer 1

Question 3

Let the number of times an odd number was chosen be x. Then, the number of times an even number was chosen is x+4.

`x+x+4=50\\\\2x+4=50\\\\2x=46\\\\x=23`

So, the answer is 23 times.

Question 4

If 8 ordered pizza, 4 did not order pizza.

`(4)/(12)=(1)/(3)`

So, the answer is 1 out of 3.
