A) \[\frac{33}{54}\]
B) \[\frac{31}{55}\]
C) \[\frac{29}{52}\]
D) \[\frac{27}{57}\]
E) None of these
Correct Answer: B
Solution :
Total number of balls\[=8+3=11\] \[\therefore \]\[n(S){{=}^{11}}{{C}_{2}}=55\] \[n(E){{=}^{8}}{{C}_{2}}{{+}^{3}}{{C}_{2}}=28+3=31\] \[\therefore \]\[P(E)=\frac{n(E)}{n(S)}=\frac{31}{55}\]You need to login to perform this action.
