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

$Pr(sum\text{7\rparen =}(6)/(36)=(1)/(6)\text{ }$
