If a school is selected at random, find the probability that the school is having (i) minimum fee

(ii) maximum fee (iii) fee of atmost Rs 1000 (iv) fee between Rs 1000 and Rs 1500

Answer 1

Hello dear,
Here is your 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

Hope u get your answer :)
