The probability that no boys will be chosen is calculated by finding the probability of selecting 2 girls out of 12, divided by the total ways of selecting 2 students out of 22. This is $\frac{{12C2}}{{22C2}} = \frac{{12! / (10! \cdot 2!)}}{{22! / (20! \cdot 2!)}} = \frac{{66}}{{231}} = \frac{2}{7}$.
