A set of outcomes of a random experiment can be defined as an event in probability. All possible outcomes of an experiment are represented by the sample space.

The three events are:

1. Individual is from age group $18-34$
2. Individual is Male
3. Individual approves of Mayor Ford

Entry $40$means that total $0.40$percent of individuals approves Mayor ford.

Compliment of $40$means that total $0.6$percent of individuals disapprove mayor ford.

Entry $30$means total$0.30$ percent of age group $18-34$approves mayor ford.

Out of males and females, total$0.44$ percent are males.

Out of total females, $0.63$disapproves mayor ford.

Out of all age group , $0.40$percent approves mayor ford.

There are $0.40$percent of individuals are male who approve mayor ford .Therefore$P\left(Approve\right|Male)=0.44$

Out of the age group the total percent that are more than $44$years old is calculated as follow:

$$\begin{gathered} P(percentmorethan44yearsold)=\frac{226+268+331}{1045} \\ P(percentmorethan44yearsold)=0.789 \end{gathered}$$

there is total $0.30$percent of those individuals are present whose age is less than$35$years and approve mayor ford. Therefore,$P\left(Approve\right|Age<35)=0.30$
