A die has  sides, with each side displaying a number between . 

Let's first determine the probability of rolling an even number after John rolls the die a single time.

There is a total of  sides on a die and  even numbers: ; thus, our probability is:

This means that roughly  of John's rolls will be an even number; therefore, in order to calculate the probability we can multiply  by —the number of times John rolls the die.

If John rolls a die  times, then he will roll an even number roughly  times. 

A die has  sides, with each side displaying a number between . 

Let's first determine the probability of rolling an odd number after John rolls the die a single time.

There is a total of  sides on a die and  odd numbers: ; thus, our probability is:

This means that roughly  of John's rolls will be an odd number; therefore, in order to calculate the probability we can multiply  by —the number of times John rolls the die.

If John rolls a die  times, then he will roll an odd number roughly  times.

Let's first determine the probability of rolling a , a , or a  after John rolls the die a single time.

There is a total of  sides on a die and we have one value of , one value of  and one value of ; thus, our probability is:

This means that roughly  of John's rolls will be a , , or a ; therefore, in order to calculate the probability we can multiply  by —the number of times John rolls the die.

If John rolls a die  times, then he will roll a , , or a  roughly  times.

Let's first determine the probability of rolling an odd number or a  after John rolls the die a single time.

Let's first determine the probability of rolling a  after John rolls the die a single time.

There is a total of  sides on a die and only one value of  on one side; thus, our probability is:

There are four cards of each rank in a standard deck; since three ranks - jacks, queens, kings - are considered face cards, this makes twelve face cards out of the fifty-two. But two of those face cards - two red queens - have been removed, so now there are ten face cards out of fifty. This makes the probability of a randomly drawn card being a face card

.

Probability is determined by dividing the number of incidences of a specific outcome (in this case rolling greater than 4, or rolling a 5 or 6) by the total number of outcomes (there are 6 sides to the die).
