Only Apple (a) and Orrange (o) in the box.
1. Information only for a, nothing for o ------------>NS
2. a:o=1:4 ------------->Suff
say a=1 & o=4 , =>n=5 hence P(a) = $$\frac{a}{n}$$= $$\frac{1}{5}$$
or say a=2 & o=8 , hence P(a) = $$\frac{a}{n}$$= $$\frac{2}{10}$$= $$\frac{1}{5}$$

Thus Ans B

1 insuff as no info for O
2 A:O 1:4 given , therefore A:total = 1:5, this will be true for ny number of values satisfying A:O 1:4 , hence P(A) = A/total fruits
=1/5, hence suff
