Probability of Event not Happening
Probability of Event not Happening
Probability of Event Not Happening:
Probability of Happening of Event + Probability of Not Happening of Event = 1
Probability of Event Not Happening = 1- Probability of Happening of Event
Example 1: We have balls number 1 to 9. What is the probability of not picking an even numbered ball.
Sol: Total number of possible outcomes= 9 as there are 9 balls.
Total Number of favourable cases = 1,3,5,7,9 Numberd ball is picked. Therefore the number of favourable cases is 5
Otherwise as in the earlier example, we have calculated the probability of occuranceas= 4/9
