Yes but we do know know how many snakes there are in the box.
For example if the number of snakes is 10 there could be 9 ; 1 or it could be 5;5.
Second one is clearly insufficient also
And both are insufficient.
99 Snakes 1 cobra 98 vipers, or 97/2
Please explain
Thank you
Let me ask you if there are 5 vipers and 5 cobras, would the second statement be correct?
Hey Bunuel, it's still not clear for me concerning answer (1).
If we take your example with 10 snakes, doesn't it mean that
we can have anything from (5V 5C; 6V 4C;...9V 1C) according to statement 1? A ratio of 6:4 V to C is still "at least 1 viper" for any 2 snakes.
Thanks for clarifying.
NO. We cannot have more than 1 cobras. If there are 5 cobras and 5 vipers then the first statement will NOT hold. (1) says from
two snakes from Pandora's box at least one is a viper. If there are 5 cobras and 5 vipers then we could have two snakes from which BOTH are vipers.
