In a survey among the readers of newspapers, it was found that 65 persons read the Prothom Alo, 40 persons read the Bhorer Kagoj, 45 read the Janakantho, 52 read the Jugantor. If one person is chosen at random from the readers, what is the probability that the person doesn't read the Jugantor?

Question: In a survey among the readers of newspapers, it was found that 65 persons read the Prothom Alo, 40 persons read the Bhorer Kagoj, 45 read the Janakantho, 52 read the Jugantor. If one person is chosen at random from the readers, what is the probability that the person doesn't read the Jugantor?

Solution:
Total persons = 65 + 40 + 45 + 52
= 202

probability of that person reading jugantor = 52/202
= 26/101

the probability that the person doesn't read the Jugantor = 1 - 26/101
= (101 - 26)/101
= 75/101
