Eureka!

I've got it!

I've got it!

moving to a new location. all things must pass.

I have many methods to calculate these type of streak problems, some including very accurate
approximations and one using Excel (or a spreadsheet) that even a 10 year old can do!
Yeah!! They be here next year.

New home is not yet ready.

WolframAlhpa does this also, Some large calculations will time out.

one can add p=0.55 to the end as an example where p is not = 0.50

try run 2 in 4 flips at 50% success

p=50%

then try run 5 in 20 flips. success = 0.2498703

then try run of 5 in 100 flips, success = 0.810109599
