Question

In a cricket match , a batswoman hits a boundary 6 times out of 30 balls she plays . Find the probability that she did not hit a boundary .

Answer 1

Step-by-step explanation:

Probability Formula

P ( A ) = Number of Favorable Outcome / Total Number Of Favorable Outcome

Number Of Ball She Played 30

Number Of Ball Went on a boundary 6

The probability is

30 - 6 / 30

= 24/30

= 4/5

All Probability Formula list

1. Probability Range 0< p ( A ) < 1
2. Probability of addition. p ( AuB ) = P ( A ) + P ( B ) - P ( AnB )
3. Rule of Complementary Event. P ( A' ) + P ( A ) = 1
4. Disjoint Event P ( AnB ) = 0
5. Independent Event P ( AnB ) = P ( A ) . P ( B )
6. Conditional Probability P ( A | B ) = P ( AnB ) / P ( B )
