Total Number of outcomes = 10 i.e. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10.
(i) P (of getting a number 7) = 1/10
(ii) P (of getting 9 or 10) = 2/10 = 1/5
(iii) Numbers greater than 4 are 5, 6, 7, 8, 9 and 10 = 6
P (of getting number greater than 4)
= 6/10 = 3/5
(iv) Numbers less than 6 are 1, 2, 3, 4, 5 = 5
P (of getting a number less than 6)
= 5/10 = 1/2
