The last three coins I found were all heads down/tails up dimes.

Last edited Sun Oct 25, 2015, 07:16 AM - Edit history (1)

I will sometimes pick up change from the ground. The last three coins I found were all tails up dimes. What are the odds that I would find three tails up dimes in a row in 6 days?

Edit: this is from all common US coins (quarters to pennies).

I'm just going to need more information. Any Kennedy half dollars? What about Susan B Anthony's or Eisenhower Dollars?
You're just going to have to use the three dimes in question to consult the I Ching. Next Find a modern New Deal candidate,
Bernie and contribute $3 . Change, up from the ground. Odds are that will work, if it doesn't remember, the house always
tilts the odds to its favor. Don't play a rigged game!!!

The odds of a tail up dime is 1/2 (heads/tails)x1/4(penny/nickel/dime/quarter). Three repeats, 1 in 24.

Ask a question. Throw those Three dimes 5 more times and record results. Consult the I Ching.

But let's say pennies, nickels, dimes, and quarters are dropped with equal frequency.

The chance of finding three dimes in a row would be 1 in 64.

The chance of them being all tails up would be 1 in 512.
