A travel company has 100 drivers for driving buses to various tourist destination. Given below is a
table showing the resting time of the drivers after covering a certain distance (in km).
Distance (in km) After 80 km After 115 km After 155 km After 200 km
No. of drivers 13
47
30
10
What is the probability that the driver chosen at random
(a) takes a halt after covering 80 km ?
(b) takes a halt after covering 115 km ?
(c) takes a halt after covering 155 km ?
(d) takes a halt after crossing 200 km ?​

Answer 1

Answer:

Total number of drivers = 13+47 +30 + 10 = 100

1) P(car taking halt after covering 80 km)= 13 100

2) P(car taking halt after covering 115 km)= 47 100

3) P(car taking halt after cvering 155 km)= 30 100

4) P(car taking halt after covering 200 km) = 10 100
