I am in my mid-eighties, trying to keep my grey cells firing by helping others with the little I know of Mathematics.

I try to keep the answers crisp, lucid and jargon-free.
The fun lies in walking the path less trodden.

Some recent examples

• There are two multisets of circles and squares. Probabilty of pulling a circle from second multiset after two transfers between the two sets

• Probability of meeting your friend on a tournament.

• Comparing the probabilities of rolling a $12$ or two consecutive $7$'s first with a pair of dice

• Getting a non natural answer for combinatorics question

• Does the probability of team A winning a series of seven games depend on whether team A plays until they win the four games needed or all seven?

• Probability of creating two same groups

• Does knowing that you drew at least $1$ ace increase the probability that you drew at least $2$ aces ($5$ card hand)?

• Arrangements of 10 red balls, 5 green balls and 5 blue balls where there can't be two adjacent balls of the same color

• Probability that 4 socks selected at random from 4 pairs will form 2 pairs
