Answer 2

Answer:

Total number of schools=14+16+18+12+14+8+8=90

i) number of schools having minimum fee ie 250−500 is 14

So required probability=favourable outcomes/total outcomes=14/90=7/45

ii) number of schools having maximum fee ie 1750−2000 is 8

So required probability=favourable outcomes / total outcomes = 8/90 = 4/45

iii)Number of schools having fee atmost Rs1000=14+16+18=48

So, Required probability=48/90=8/15

iv) Number of schools having fee between Rs1000 and Rs1500=12+14=26

Required probability=26/90=13/45
