In a class of 25 students, 17 like volleyball, 15 like basketball and 10 like both game. Find the number of students who don't like
Any of the games ​

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.

think about it deeply and passionately about this property

i am sorry

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides
