Question

A point is randomly chosen on the grid below

What is the likelihhood that the point is in the blue section of the grid ?
 
- certain 
- impossible
- likely 
- impossible

Answer 1

You have a rectangle that consists of 20 square cells. Among them are 6 blue cells.
The probability that the point is in the blue section of the grid is:


`P=(6)/(20)=(3)/(10)=0.3`.

Then you can conclude that it is likely that the point is in the blue section of the grid.

Answer 2

Answer: unlikely

Explanation:

When we consider the given grid in the picture, we observe that

Number of blue sections = 6

Total number of sections = 20

If a point is randomly chosen on the grid below,

Then the probability that the point is in the blue section of the grid will be :

`\text{P(Blue)}=\frac{\text{No. of blue section}}{\text{Total sections}}\\\\=(6)/(20)=0.3`

We know that when probability of any event lies between 0 and 0.5 then we call the event is unlikely to happen.

[Note : If probability is 1 then it is certain , if probability is 0 then it is impossible and if it lies between 0.5 and 1 then we call it likely.]

Hence, the likelihood that the point is in the blue section of the grid = unlikely.
