because in a die on

1

2

3

4

5

6

digits are present so other than these digits probability will be 0

Answer 2

SOLUTION

TO CHOOSE THE CORRECT OPTION

The probability of getting the number 9 in a die

a. 6

b. 7

c. 0

d. 2

CONCEPT TO BE IMPLEMENTED

In any random experiment if the total number of elementary ( simple) events in the sample space be n ( a finite number) among which the number of elementary events favourable to an event E , connected with the experiment be m then the probability of the event E is denoted by P (E) and defined as

$\displaystyle \sf{}P(E) = \frac{m}{n}$

For an impossible event, the number of favourable cases is zero and hence it's probability is 0

On the other hand for a certain event S all cases are favourable cases and hence it's probability is 1

EVALUATION

Here the given event is of getting the number 9 in a die

A dice has 6 faces

The faces are 1 , 2 , 3 , 4 , 5 , 6

So there is no face named as 9

Therefore it is impossible of getting the number 9 in a die

Thus the event is impossible event

Hence the required probability = 0

FINAL ANSWER

Hence the correct option is c. 0
