Table S.2 shows the outcomes obtained in 250 rolls of a die 

HOW COME THE MEDIAN BE FOUR . PLEASE EXPLAIN

[Vinayak Kumar]

first you find out all the relative frequencies given, you will get a equation as x+z=95
then find out second eqn given in the ques that is difference x-z=15
solve both the eqn 

get the values 

now u know median is the middle most value or using formula for even no. of observations
you will get 125th and 126th observation
now count the frequency in the table you will get 125th obs in 4 rolled dice number.

Kvinay,

can you please do it on paper and show it please?

I also got the same doubt

[gayathri devi]

Difference between two relative frequency ie. X/250 - 60/250. Solving we will get 15. 

Ie. X =60+15. X= 75.

Please let me know if the above is correct.

@Vinay, Sorry, I got the question wrong. i assumed the value as 6 instead of 5

Thanks

[Vinayak Kumar]

here is solution
