From the graph we can observe the number of readers of each newspaper. It is -
Hindustan Times - 35
Economic Times - 45
Total families = 50
(Since the graph has highest capacity of 50)
Probability of Family reading Hindustan times = 35/50 = 7/10
Probability of family reading Economic Times = 45/50 = 9/10
Now, probability that a family chosen at random is taking both the newspapers = 7/10 × 9/10 = 63/100
Hindustan Times - 35
Economic Times - 45
Total families = 50
(Since the graph has highest capacity of 50)
Probability of Family reading Hindustan times = 35/50 = 7/10
Probability of family reading Economic Times = 45/50 = 9/10
Now, probability that a family chosen at random is taking both the newspapers = 7/10 × 9/10 = 63/100

Okay okay sorry ..u will not :)
i think you have to put answer as zero
Uhh...U do whatever u want..if the guy says the no. of families isn't that..u can either edit it or leave it as it is....i don't mind either
I had previously approved yours thinking it was right though it came out to be wrong according to him but it would be better if u edit it a wish of inquirer..
it's quite confusing u see...i better not eavesdrop is the math corner next time...
Just leave it as it is.. and keep up ur good work here..ur answers r really nice ..
Well stop wasting your time I have already answered it correctly
Good to see you again Mrs Divya
@k23 I am not Mrs.Divya @Lipimishra2 Thanks and well I think you should not have deleted your answer because it is not mentioned so in the question.If we write zero as the answer, our answer would be wrong according to the question.If anyone wants to see its answer in the archive he would misunderstand it as zeeo.So, better this is correct and if the data is given thn only we should change our answer.Hope u get it :)
And yes please don't spam by commenting here.If you have any doubt then u can Pm(private message) me.. Thankyou!

Total number of families is 138
So the required probability is 35+45= 80
Probability = 80÷138
Well I am not sure about it

Well I think you should complete ur answer.Please correct it :l
