A) \[\frac{4}{5}\]
B) \[\frac{7}{8}\]
C) \[\frac{8}{7}\]
D) \[\frac{1}{2}\]
E) \[1\]
Correct Answer: B
Solution :
\[S=(BBB,\text{ }BBG,\text{ }BGB,\text{ }GBB,\text{ }GGB,\text{ }GBG,\] \[BGG,\text{ }GGG\}\] and\[E=\{BBB,\text{ }BBG,\text{ }BGB,\text{ }GBB,\text{ }GGB,\text{ }GBG,\] \[BGG\}\] \[n(E)=7\]and\[n(S)=8\] \[\therefore \] \[P(E)=\frac{n(E)}{n(S)}=\frac{7}{8}\]You need to login to perform this action.
