Answer 1

14. given points (-1 ,7) and (4,-3) ratio = 2:3

(x,y)=(mx2+nx1/m+n , my2+ny1/m+n)

here m:n = 2:3

(x,y) = 2×4+3×-1/2+3 , 2×-3+3×7/2+3

(x,y) = 8-3/5 , -6+21/5

(x,y) = 5/3, 5

OR

p( getting a king of red colour) = 2/52=1/26

p(getting a face card) = 12/52=3/13

p(getting a spade) =13/52
