How many possible outcomes are there when a coin is tossed four times?

Two four sided die, numbered 1 to 4 are tossed and their sum is recorded. By using a table determine the probability of scoring a sum of 6.

A two digit number is formed using the digits 1, 2, 3. The same number can be used twice. The first number is the tens digit and the second digit is the units digit. By using a tree diagram, determine the probability of forming a number less than 23.

There are three questions in a True or False quiz. By drawing a tree diagram, determine the probability of randomly selecting at least one false answer.

A dice is tossed twice. What is the probability of getting 2 numbers greater than 5?

There are 6 balls in a box, 4 blue and 2 red. What is the probability if 2 balls are taken out, that at least one of the balls is blue?

There are 12 chocolates in a box. 4 chocolates have soft centres, 4 chocolates have hard centres and 4 have nut centres. What is the probability that if you choose 2 chocolates and eat them, they have the same centres?

A bowl of fruit contains 16 apples of which 10 are red and 6 are green. Bill takes one apple at random and eats it. Ben also takes an apple at random and eats it. 

By drawing a tree diagram, or otherwise, find the probability that Bill and Ben eat apples that are different in colour. 

A 4 sided die and a 6 sided die are tossed together and the numbers are added together as indicated in the table. What is the probability that their sums are less than 5?

There are three questions in a True or False quiz. By drawing a tree diagram, determine the probability of randomly selecting one false and two true answers.
