Answer:


Step-by-step explanation:

n=60

i) 16,25,36,49,64       n(I)=5

p(i)=5/60 = 1/12

.......................................................

ii)  11,13,17,19,23,29,31,37,41,43,47,53,59      n(ii)=13

p(ii)=13/60

...................................................

iii)  15,20,25,30,35,40,45,50,55,60     n(iii)=10

p(iii)=10/60=1/6

...........................................

iv) 14,21,28,35,42,49,56   n(iv)=7

p(iv)=7/60

......................................

v)  n(v)=30

p(v)=30/60=1/2

...............................................
