- Three boxes \(\mathrm{B}_1, \mathrm{~B}_2\) and \(\mathrm{B}_3\) contain balls with different colors as follows:
\begin{array}{cccc}
& White & Black & Red \\
\mathrm{B}_1 & 2 & 1 & 2 \\
\mathrm{~B}_2 & 3 & 2 & 4 \\
\mathrm{~B}_3 & 4 & 3 & 2
\end{array}
A die is thrown. Box \(B_1\) is chosen if either 1 or 2 turns up. Box \(B_2\) is chosen if 3 or 4 turns up and box \(B_3\) is chosen if 5 or 6 turns up. Having chosen a box in this way, a ball is drawn at random from that box. If the ball drawn is found to be Red, then the probability that it is drawn from box \(\mathrm{B}_2\) isAP EAMCET 2023 Easy - Given that \(a, b \in\{0,1,2, \ldots, 9\}\) with \(a+b \neq 0\) and that \(\left(a+\frac{b}{10}\right)^x=\left(\frac{a}{10}+\frac{b}{100}\right)^y=1000 . \quad\) Then, \(\frac{1}{x}-\frac{1}{y}\) is equal toAP EAMCET 2008 Hard
