Solution

## Given we can choose a number from $1$ to $11$.Total number of outcomes $=11$From $1$ to $11$, odd numbers are $1,3,5,7,9,11$The number of favorable outcomes $=6$We know that $\mathrm{Probability}=\frac{\mathrm{number}\mathrm{of}\mathrm{favorable}\mathrm{outcomes}}{\mathrm{total}\mathrm{number}\mathrm{of}\mathrm{outcomes}}$ $=\frac{6}{11}$Therefore the probability of choosing an odd number from $1$ to $11$is $\frac{6}{11}$.
