The probability the minute hand lies from $5$ to $15$ min in a wall clock is 

The diameters of a circles (in $\mathrm{mm}$ ) drawn on a table are given below. If a circle is chosen at random, then the probability that chosen circle has diameter less than $28$.

The diameters of circles (in $\mathrm{mm}$) drawn on a table are given below:

If a circle is chosen at random, then find the probability that chosen circle has radius lying between $14$ to $17$.

The diameters of circles (in $\mathrm{mm}$) drawn on a table are given below:

If a circle is chosen at random, then find the probability that chosen circle has diameter above $50$.

In the given figure, points $A, B, C$ and $D$ are the centres of four circles that each have a radius of length one unit. If a point is selected at random from the interior of square $ABCD$, then the probability that the point will be chosen from the shaded region, is
