4aiii) probability that the no. is shaded : 4/10
prob. that the no. is even : 5/10
4/10 + 5/10 = 9/10
however, it cant be 2 or 4, because they're shaded and even...prob. of getting 2 or 4 = 2/10
9/10 - 2/10 = 7/10
biv) possibilities : (1,1) (2,1) (1,2)
(1,1) = 1/10 * 1/10 = 1/100
(2,1) = 1/100
(1,2) = 1/100
1/100 + 1/100 + 1/100 = 0.03
