Problem:

 Find the largest value of n for which BetaRegularized[1-p0,n-c,c
+1]>=1-alpha.

 Find the smallest value of n for which BetaRegularized[1-p1,n-c,c
+1]<=beta.

0<p0<p1<1, 0<alpha<1, 0<beta<1, c is a positive integer.

Values of p0, p1, alpha, beta and c are specified.

Since BetaRegularized[1-p0, n-c,c+1] decreases as n increases, the
required value of n satisfies the equation, BetaRegularized[1-p0,n-c,c
+1]=1-alpha.

Since BetaRegularized[1-p1, n-c,c+1] decreases as n increases, the
required value of n satisfies
the equation, BetaRegularized[1-p1,n-c,c+1]=beta.

My attempts to use Solve to find the required values of n were
unsuccessful. Hints or suggestions would be appreciated.

John
