8. A die is tossed 270 times and the result were as follows:
 
Outcomes 6 1 2 3 4 5
Frequencies 18 40 56 60 32 55

Find the probability of getting either 1 or 3?

9. In a cricket match, a batsman hits a boundary 6 times out of 36 balls he plays. Find the probability that he did not hit a boundary?

  • 2
Frequency of 1 as an outcome is 40
Frequency of 3 as an outcome is 60

So, P= 60 + 40/ 270
=> 100/270= 10/27

9.=> Number of balls= 36
No. of times he hit= 6
Probability of not hitting the ball= 30/36
=> 5/6
