Question

Six pupils obtained the following marks in mathematics contest 23, 24, 39, 40, 26, 37 find the probability that a pupil selected at random obtained more than 27 marks

​

Answer 1

39, 40 and 37 are the only number above 27
This will lead us to have 3/6

Answer 2

In order to find the probability that a pupil selected at random obtained more than 27 marks, we need to know the total number of pupils and the number of pupils who scored more than 27 marks.

Let's call the total number of pupils "n" and the number of pupils who scored more than 27 marks "x".

From the given data, we know that n = 6 and the pupils who scored more than 27 marks are 39, 40, 37.

x = 3

Now we can use the formula for probability:

Probability = (x/n)

Probability = (3/6)

Probability = 0.5

So the probability that a pupil selected at random obtained more than 27 marks is 0.5 or 50%.
