A certain parking lot has three entrances. 40% of drivers use entrance 1 (A1), 35% use entrance 2 (A2), and 25% use entrance 3 (A3). Of those drivers using entrance 1, 30% park for more than two hours (event B). Of those drivers using entrance 2, 60% park for more than two hours, whereas of those using entrance 3, 50% park for more than two hours. What is the correct probability notation to represent 40%

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
