Question

3)The probability of scoring 40
marks in a 50 mark test is​

Answer 1

Answer:

P(E)=1/50

Step-by-step explanation:

Total no of possiblites=50 ,since there are 50 marks

Possible outcomes=1,since 40marks is one of the outcome out of the 50marks

Therefore probability is

=Possible outcomes/Total no of outcomes

P(E)=1/50

Hope it helped :)

Answer 2

Given:

Total marks= 50

Marks to be scored= 40

To find:

The probability of scoring 40 marks in a 50 mark test

Solution:

For finding probability of any occurrence=

Number of events/Total number of outcomes

In this case, the total number of outcomes is 50( as total marks is 50 and the student can score any marks)

The number of events is 1 as there can be only one occurrence of scoring 40.

So, probability of scoring 40 marks in a 50 mark test= 1/50
