The inverse binomial cumulative distribution function results in the
minimum number of successes, such that the cumulative probability for
that minimum number of successes ≥ the given cumulative probability
(area). If more information is needed, also find the binomcdf for the
result from invBinom(as shown below for a full analysis.

Details:
Assume the toss of a fair coin 30 times. What is the minimum number
of heads you must observe such that the cumulative probability for that
number of observed heads is at least 0.95?
The results on the screen first show that the minimum number of
successes to obtain at least the given cumulative probability of 0.95 is
19. Next, the cumulative probability for up to 19 is computed using
binomcdf(and is approximately 0.9506314271 which meets the criteria
of 0.9506314271≥0.95
Alternate Method:
Set Y1=binomcdf(30,0.5,X) and use the table of values (starting at 0 and
increment by 1) to find when the cumulative probability is at or just
above the given cumulative probability. This gives you a view of all
values to make decisions. For this example, search in the table to find
the cumulative probability just larger than 0.95. Again, the number of
