A Crazy Die has 5 sides, but each side has a different probability of being rolled. This is is the probability distribution of the sides being rolled:
| | 0.3 | 0.25 | 0.1 | 0.25 | 0.1 | | 1 | 2 | 3 | 4 | 5 | | Number |
What is the probability of rolling a number from 4 to 5? | |
[1] | You roll 2 3-sided dice
You add the two numbers. What is the probability of getting exactly 5? | |
[1] |
| A bag has 4 balls with number 5 and 6 balls with a number 5. What will be the average of the numbers of the balls taken out of the bag | |
[1] | You flip a coin and roll a 6 sided die.
What is the probability of getting a 5 or a 5 and a tail? | |
[1] |
Flip a coin 14 times.
Each time a Tail comes up you win $1. It costs $17 to play (paid once). How much money would you expect to make altogether? | |
[1] | A group of humans did a math test and here are their scores out of 5:
What fraction of the humans score less than 3? | |
[2] |
You roll a 3 sided die and a 7 sided die.
What is the probability of getting 1 on both dice? | |
[1] | A group of boys were timed running 100m. Here are the results:
What fraction of the boys run 100m in exactly 16s?

A group of boys were timed running 100m. Here are the results:
What is the probability of the boys to run 100m in exactly 16s?
| |
[2] | We asked a group of boys how many Hot dogs they eat in a day. Here are the results:
What fraction of the boys eat less than 4 Hot dogs in a day? | |
[2] |
Roll a die 36 times.
How many times would you expect to get a 4? | |
[1] | There are 70 balls in a bag. This is is the probability distribution of their color:
If you choose a random ball from the bag, what is the probability of it being red? | |
[1] |
Roll 1 6-sided die.
What is the probability of getting a 3? | |
[1] | A group of humans were timed running 100m. Here are the results:
| Time | humans | | 13 | 4 | | 14 | 3 | | 15 | 2 | | 16 | 6 | | 17 | 1 |
What is the probability of the humans to run 100m in exactly 16s?
