Best guess for next-round probability of success is 0.75, not 0.8!
"p" equals StartFraction, "r" Over "n" , EndFraction equals 0.8p=rn=0.8

Start integral from 0 to 1, end integral, "p" "f" ( "p" ) "d" "x" equals StartFraction, "r" plus 1 Over "n" plus 2 , EndFraction equals 0.7 5∫10pf(p)dx=r+1n+2=0.75
So far, 8 out of 10 trials (0.8) have been successes.
Thus our best guess for
"p"p
is 0.8.
However, our best guess for the probability of the
