Hi, I have two questions which I think are easy but I am not sure as I am starting to learn probability.

1. We have 32 integers from 1 to 32. we choose 16 of them

randomly. what is the probability of the integer 32 being chosen?

2. We

have 32 integers from 1 to 32. We will choose 4 from them.

The

probability of choosing one integer is its value divided by total of all

integers.

For example, if there is 4 integers, the total of them is 4+3+2+1

= 10

so probability of selecting 1 is 1/10

probability of selecting 2 is

2/10

probability of selecting 3 is 3/10

probability of selecting 4 is

4/10

Using the above method we will choose 4 integers out of 32. What is

the probability of 32 being chosen?
