Poisonous Drink

Marissa and Juliana went out for drinks together. They ordered the same drink. Juliana was really thirsty and finished five in the time it took Marissa to finish one. The drinks were poisoned, but only Marissa died. How?



TIP : Poison wasn't in Marrisa's glass neither added externally by any one.

This is how Juliana survived! 

Harmless Poisonous Drink


What was the incident?

That's because the poison was in the ice. Since Marissa took time to drink her first, the ice melted & poison got mixed up in the drink very well. Whereas, Juliana was thirsty & finished drinks in hurry; it didn't get enough time to melt the ice & hence poison didn't get mixed up with the drink. That's how Juliana survived!

"The Most Likely Total !"

A fair die bearing the numbers 1, 2, 3, 4, 5, 6 is repeatedly thrown until the running total first exceeds 12. What’s the most likely total that will be obtained?

"The Most Likely Total !"



This must be the most likely total!

Findiing The Most Likely Total


Here is the question!

Just consider the the next-to-last throw where last throw would make total exceeding 12.

Till then total must be either of 12,11,10,9,8 or 7. And next throw will make total greater than 12.

At this point - 

If total is 12 then the first total exceeding 12 could be any from 13,14,15,16,17,18.

If total is 11 then the first total exceeding 12 could be any from 12,13,14,15,16,17,

If total is 10 then the first total exceeding 12 could be any from 12,13,14,15,16.  

If total is 9 then the first total exceeding 12 could be any from  12,13,14,15. 

If total is 8 then the first total exceeding 12 could be any from 12,13,14. 

If total is 7 then the first total exceeding 12 could be any from 12,13.

It's quite evident that the number 13 appears in every above case.

Hence, 13 is the most likely total.
