Dear

Please complete qns

Answer 2

Answer:

X => 1,2,3,4

Y=> 1,4,9,16

TO FIND - probability that XY < 25

total events = 16

(1,1)(1,4)(1,9)(1,16)

(2,1)(2,4)(2,9)(2,16)

(3,1)(3,4)(3,9)(3,16)

(4,1)(4,4)(4,9)(4,16)

outcomes where XY < 25 = 11

(1,1)(1,4)(1,9)(1,16)

(2,1)(2,4)(2,9)

(3,1)(3,4)

(4,1)(4,4)

probability = 11/16
