In a cricket match, a batsman hits a boundry 6 times out of 30 balls he plays.
Find the probability that on a ball played :
(i) he hits boundry
(ii) he does not hit a boundry.
Given,
Number of times batsman hits the boundry = 6
Total balls played = 30
Number of times that batsman does not hit the boundry = 30-6 = 24
Probability (number of times he hits a boundry) = 
Probability (number of times he does not hits a boundry) =
