A) \[\frac{({{2}^{10}}-1)}{{{2}^{20}}}\]
B) \[\frac{({{2}^{10}}-1)}{{{2}^{10}}}\]
C) \[\frac{^{20}{{C}_{10}}}{{{2}^{10}}}\]
D) \[\frac{^{20}{{C}_{10}}}{{{2}^{20}}}\]
Correct Answer: D
Solution :
Required probability is\[\frac{{{\left( ^{10}{{C}_{0}} \right)}^{2}}+{{\left( ^{10}{{C}_{1}} \right)}^{2}}{{\left( ^{10}{{C}_{2}} \right)}^{2}}+.........{{\left( ^{10}{{C}_{10}} \right)}^{2}}}{{{2}^{10}}}\] \[\frac{^{20}{{C}_{10}}}{{{2}^{10}}}\]You need to login to perform this action.
