Solution
Use a tree diagram to determine the probability of tossing a total of 7 using two regular dice.
For the sum number hould be 7
First dice : 1 2 3 4 5 6
second dice 6 5 4 3 2 1
Probability = favourable outcomes /total outcomes
Pro(total sum of 7) = number of seven / Total number
[tex]Pr(sum\text{7\rparen =}\frac{6}{36}=\frac{1}{6}\text{ }[/tex]
