(D) Total balls = $25$. Odd numbers between $1$ and $25$ are ${1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25}$,which are $13$ in total. Probability of success $(p)$ = $\frac{13}{25}$. Probability of no success $(q)$ = $1 - p = 1 - \frac{13}{25} = \frac{12}{25}$. Since $2$ balls are drawn with replacement,the trials are independent. Probability of getting no success in $2$ draws = $q 	imes q = \frac{12}{25} 	imes \frac{12}{25} = \frac{144}{625}$.

An urn contains $25$ balls numbered $1$ to $25$. Suppose an odd number is considered a 'success'. $2$ balls are drawn from the urn with replacement. Find the probability of getting no success.
