Answer

$0.5$

Work Step by Step

We know that $probability=\frac{number \ of \ good \ outcomes}{number\ of\ all\ outcomes}$. An orange has two hemispheres: the northern and the southern. There are $2^{2}=4$ opportunities from which two are good (both southern or both northern), therefore the probability is $\frac{2}{4}=0.5$.
