Q10. Permutation 1.... i did lyk this...
part 1.. 9!
part 2.. 2!*8! ... this was the arrangement of pink and green together... subtract it from 9! u'll get arrangement of not together..
part 3.. 9p3 * 3!.... u have to arrange 3 cards aswell...
part 4.. 8p2 * 3! .. as pink card is fixed..

Guys... was the answer for the X<mew question coming like mew=-1.5 something s.d?
It was coming negative....
Central tendency question was weird but i used Q1 Q2 Q3 and IQR. I don't know how people calculated mean? That was totally impossible. Does that mean we had to make a box and whisker plot?

All in all the paper was weird
