A parent has collected data of number of school based on the monthly fees, so that he can choose the school for admission of his child. Data is as follows:
Monthly school fee (in Rs) | 250-500 | 500-750 | 750-1000 | 1000-1250 | 1250-1500 | 1500-1750 | 1750-2000 |
No. of Schools | 14 | 16 | 18 | 12 | 14 | 8 | 8 |
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
