## Question

###### A recent study by the Lembaga Lebuhraya Malaysia revealed that20 percent of Malaysian drivers do not use their seat belts. (a) A sample of 15 driversis selected. What is the probability that: (i) 4 or fewer of the drivers are not wearing seatbelts? (2 m)(ii) more than 6 of the drivers are not wearing seatbelts? (2 m)(iii) less than 4 or more than 10 are not wearing seatbelts?

A recent study by the Lembaga Lebuhraya Malaysia revealed that 20 percent of Malaysian drivers do not use their seat belts. (a) A sample of 15 drivers is selected. What is the probability that: (i) 4 or fewer of the drivers are not wearing seat belts? (2 m) (ii) more than 6 of the drivers are not wearing seat belts? (2 m) (iii) less than 4 or more than 10 are not wearing seat belts? (3 m) (b) Calculate the mean, variance and standard deviation of the number of drivers who do not wear seat belt in a sample of 1000 randomly selected drivers. #### Similar Solved Questions
