# 6. Find the probabilities of the events given in Question 2.2. When a die is thrown, list the outcomes of an event of getting(i) (a) a prime number    (b) not a prime number.(ii) (a) a number greater than 5     (b) a number not greater than 5.

Total outcomes = 6

6.(i) (a) prime numbers = 2,3,5 = 3 numbers

probability of prime number

$=\frac{3}{6}=\frac{1}{2}$

(b) non prime numbers = 1,4,6 = 3 numbers

probability of non prime number

$=\frac{3}{6}=\frac{1}{2}$

(ii) (a) number greater than 5 = 6  = 1 number only

probability of getting number greater than 5

$=\frac{1}{6}$

(b) number not greater than 5 = 1,2,3,4,5 = 5 numbers.

probability of getting number not greater than 5

$=\frac{5}{6}$
