Question

answer 5 th one fast

Answer 1

the events is not a possible event


so p(e)=n(e)/n(s)

n(e) =0
n(s)=5
p(e)=0/5=o

so it is a impossible event

Answer 2

a=2 , d=3

a=a1= 2
a2=a+d=2+3=5
a3=a+2d=2+(2)3=8
a4=a+3d=2+(3)3=11
a5=a+4d=2+(4)3=14


A.P =2,5,8,11,14

in this AP multiple of 3 are none

so probability of getting a multiple of 3 is 0
