Didnt get the last one, atleast 4 non- face cards.
In the gloves question.
How does case a and b differ from each other.
I am not able to differentiate the situations or rather the answers.
A) We need only 4 chances. Why am I not exhausting all the pairs not required by me and then getting the one that is favourable. Ans would then be 37
I am getting 37 for the third question in the exercise.
worst-case scenario should be picking 9 cards of each suit = 9*4 + 1 ?
Where am I going wrong ?
Harsh, the questions is about colours and not suits. Only 2 colours so 9*2+1 = 19..
Oh yes !
Thanks a lot !
HAHAHA.. i dont knw know wht it is..i was finding this concept for months .. and i got today..just before my cat 😀
the worst case situation for last question will be 3 face cards..and as suite is not mentioned at all… ‘so three face cards from all suits’….. i.e. 3×4 = 12 + 1 = 13
No, the worst case will be where we pick all 12 face cards available, and 3 non-face cards (15 in total)
In the last question, Why are we adding 3 non-face cards, shouldn’t it be 12+1=13 only?
Because we want four non-face cards, not just one. So in the worst case, I might pick up 12 face cards, I need at least 4 more to guarantee 4 non-face cards.
