Answer
$\frac{3}{5}$
Work Step by Step
We know that $probability=\frac{\text{number of favorable outcomes}}{\text{number of all outcomes}}$
The number of all outcomes is $22+18+10+18+20+12=100$, out of these $10+18+20+12=60$ correspond to the desirable selection.
Hence here the probability is $\frac{60}{100}=\frac{3}{5}$
