Solution :

n(S) = Total number of elementary events= 12. <br> (i) Favourable number of elementary events that points to 10 = 1 <br> `therefore " Required probability "(1)/(12)` <br> (ii) Let A be the event "point of the arrow head towards an odd number" <br> `therefore" "n(A)={1,3,5,7,9,11}=6` <br> `therefore" "P(A)=(n(A))/(n(S))=(6)/(12)=(1)/(2)` <br> (iii) Let E be the event "pointing towards a number which is a multiple of 3" <br> `therefore" "n(E)={3,6,9,12}=4`<br> `therefore" "P(E)=(n(A))/(n(S))=(4)/(12)=(1)/(3)`
