Question

The bar graph shows the number of representatives from the north,south,central,east and west regions of a city

according to the bar graph what is the experimental probability that a randomly chosen representative is from the west region?
A)1/6
B)1/12
C)1/5
D)1/3

Answer 1

1/6 i believe since there are 2 rep from that region and there are 12 in total

Answer 2

The answer is
`(1)/(6)`

Explanation:

In order to determine the probability, we have to determine the total amount of representatives and then the total amount of representatives from west region.

In probability, there is a formula called "Classical probability", that is:

Let A=Numbers of favorable outcomes

B=Total number of possible outcomes

Probability of an event=
`(A)/(B)`

So, the representatives of each region are:

North=1

South=4

Central=2

East=3

West=2

Total representatives=12

Therefore, the probability of a chosen representative from west region is:

`P=(2)/(12)=(1)/(6)`
