Curious on how to calculate this probability because mathguys.com is down ours40:

I s this 1/16 cross multiplie with 9/16? 

 

 

[Dinsy Ejotuz]

It's a binomial with a .0625 chance of hitting.

Odds it hits 9/19 (or more) is 1 in 1,325,024.

I was told there would be no math.

It's a binomial with a .0625 chance of hitting.

Odds it hits 9/19 (or more) is 1 in 1,325,024.

Exactly what I was gonna say.

Nice job.

Round or square?

I'm embarrassed, I have a math degree and no clue how to solve the OP

Same.  Exactly 9 is easy.  Trying to recall the combinatorical trick to get 9+ though.  One of the few books I kept over the years, might have to look it up later.

 

[belljr]

Yeah sure easy

Switch your choice.  It's 66 vs 33 chance of being right.
