50÷571total no of outcomes=571 and accident done by driver of age 30 to 50 years are 50 such driver who have done accident 2 times

Answer 2

7)

50 = no. of accidents of the age group 30 to 50.

571 = total no. of drivers in the age group of 30 to 50.

Hence, probability of drivers of age group 30 to 50 having only 2 accidents in a year is 50/571.

8)

No.of days forecast was correct = 105

Total no. of days in the year 2007 = 365

Hence, probability of correct weather forecast is 21/73.

Frequency of dice showing 2 = 30

No. of times dice was thrown = 200

Hence, probability of dice showing 2 is 3/20.
