A) 1/4
B) 1/2
C) 3/4
D) 1/8
Correct Answer: B
Solution :
Let A be the event such that sum is Rs. 20 or more \[\therefore \]\[P\text{ }\left( A \right)\text{ }=\text{ }1\text{ }-\text{ }P\] (Total value is < 20) \[=1-\frac{^{6}{{C}_{2}}{{-}^{2}}{{C}_{2}}}{^{8}{{C}_{2}}}=1-\frac{14}{28}=1-\frac{1}{2}=\frac{1}{2}\]You need to login to perform this action.
