Eureka!

I've got it!

I've got it!

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 coming soon.

New home is ready.

Here are links NOT to visit

they are close, maybe, how close do you wants?

there are 2 I found that works very well and accurate.

The 1st rounds to 2 places for accuracy

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
