are you sure
actually my classmates said that we had to shade boxes in some order so i am confused about it
what answers did you got in next two parts related to possibility diagram?

 

[M.Omar]

?
Shade?No we had to fill in the numbers...

The possibility diagram....we had to shade in regions representing 2/2, 3/3, 5/5, 7/7 and like tht cos we cant have 2 draws and pick the same same ball twice cos there was no replacement..

Are you guys sure kay frequency density ka graph banna tha because they didnt mention it.
Most of my friends and I made for frequency.
And for the one saying, histogram is only made by frequency density, no sir. You can make a histogram of frequencies aswell.

I think it was frequency. Since everybody or most of us did that frequency density thing so I just don't want everybody to turn against me.
The thing is I checked past papers that redspot thing, I know that's not very reliable but still. One more thing almost in every paper where they ask about f.d they do make atleast two bars already. This is not something hard and fast but this is something I've noticed.

But the rule is to make a histogram with f.d. I used to make it with frequency in my school and got my marks deducted for that
