Question

Hint:

**Hint:**

The probability of an event A is given by

P(A)= m/n, where n=total number of possible outcomes and m=number of outcomes favaur able to event A.

Here, we have a table which shows the distribution of single-story and two-story houses in a neigh bur hood classified according to roof type- Asphalt shingle, slate, and cedar shake. We need to find the probability of selecting a single story house with slate roof.

## The correct answer is:

### Let A be the event that the house selected at random is a single storey house with slate roof.

From the table given, it can be seen that

The number of houses which are single storey having slate roof =4.

Total number of houses =48

So,

The number of outcomes favourable to A (m)=4

Total number of outcomes (n)= 48

Hence, the probability of selecting a single storey house with slate roof,

Thus, the correct option is A)

**Note:**

The definition of probability used above is the definition of theoretical probability or classical probability. There are many other terms in the concept of probability that the student must be familiar with to solve this question, such as event, outcome, favour able outcome, etc.
