A) \[\frac{25}{127}\]
B) \[\frac{50}{127}\]
C) \[\frac{75}{127}\]
D) \[\frac{100}{127}\]
Correct Answer: B
Solution :
Number of cartons left with storekeeper |
\[=250-10=240\] |
Number of cartons he bought =14 |
\[\therefore \] Total number of cartons are with storekeeper now \[=\text{24}0+\text{14}=\text{254}\] |
So, P (selecting a tetrapack of pineapple juice from store) |
\[=\frac{(90-4+14)\times 10}{254\times 10}=\frac{100}{254}=\frac{50}{127}\] |
So, Option [b] is correct. |
