Solution :
[b] Require number of ways \[{{=}^{2}}{{C}_{1}}{{\times }^{2}}{{C}_{1}}{{\times }^{4}}{{C}_{2}}{{+}^{2}}{{C}_{1}}{{\times }^{2}}{{C}_{2}}{{\times }^{4}}{{C}_{1}}\] \[{{+}^{2}}{{C}_{2}}{{\times }^{2}}{{C}_{1}}{{\times }^{4}}{{C}_{1}}{{+}^{2}}{{C}_{2}}{{\times }^{2}}{{C}_{2}}{{\times }^{4}}{{C}_{0}}\] \[=2\times 2\times \frac{4\times 3}{2}+2\times 1\times 4+1\times 2\times 4+1\times 1\times 1\] \[=24+8+8+1=41\]You need to login to perform this action.
