A) 1/14
B) 1/7
C) 5/14
D) 1/50
Correct Answer: A
Solution :
A = Events that sum of the digits on selected ticket is 8 \[=\{08,\text{ }17,\text{ }26,\text{ }35,\text{ }44\}\] \[n(A)=5\] Event that product of digits is zero \[=\{00,01,02,03,04,05,06,07,08,09,10,20,\] \[30,40\}\] \[\Rightarrow \] \[n(B)=14\] \[P\left( \frac{A}{B} \right)=\frac{5}{14}\]You need to login to perform this action.
