Question

Im not the best at word problems please help :/

Answer 1

`P(A\text{ or B)=}(13)/(19)`

Explanation:

Probability is represented by the following equation;

`P(A)=\frac{\text{ Numer of possible outcomes}}{\text{Total of the population}}`

The probability of two disjoint events A or B happening is

`P\mleft(AorB\mright)=P\mleft(A\mright)+P\mleft(B\mright).`

Then, as we can see on the table:

Let A be for graduated students

Let B Off-campus housing

Total of students: 19

`\begin{gathered} P(A)=(3)/(19) \\ P(B)=(10)/(19) \\ P(A\text{ or B)=}(3)/(19)+(10)/(19) \\ P(A\text{ or B)=}(13)/(19) \end{gathered}`
