(35) A die is thrown once. Find the probability of getting

(i) a prime number;

(ii) a number lying between 2 and 6;

(iii) an odd number.

Answer :

(i) When a die is thrown for one time, total number of outcomes =

No. of outcomes favourable to a prime number =

∴ Probability of getting a prime =
No. of favourable outcomes
Total no. of outcomes
 =
=
1

(ii) No. of outcomes favourable to a number lying between 2 and 6 =

∴Probability of getting a number between 2 and 6 =
No. of favourable outcomes
Total no. of outcomes
 =
=
1

(iii) Number of outcomes favourable to an odd number =

∴ Probability of getting an odd number P(odd) =
No. of favourable outcomes
Total no. of outcomes
 =
=
1
