In a binary system how many consequetive outcome A would be needed to show the probability of outcome B is less than 0.25 to 90 percent confidence?

In case I haven't explained that very well here's an example:
I have a bag containing black and white balls and I think that one quarter of the balls are black. I start drawing balls from the bag (and putting them back afterwards) and I keep drawing out white balls. If I were continue to pick only white balls how many times would this have to happen before I was 90% sure that less than ¼ balls were black?
Thanks

Why can't a probability be greater than 1?
Probability is the chance something is going to happen. It has to be DO/PO DO= desired outcome PO= probable outcome. The probability can not be 1 because it has to be a percent chance of out of a fraction, which are both smaller than 1.
How do you find the percent of probability?
You multiply the probability by 100.
What would happen to the width of the confidence interval if the level of confidence is lowered from 95 percent to 90 percent?
decrease

80%
Can there be a probability greater than 100 percent?
no

What does a 95 percent confidence interval tell you about the population proportion?
There is a 95% probability that the true population proportion lies within the confidence interval.

How do you interpret the adjusted odds ratio?
The best way to interpret an adjusted odds ratio is to measure its exposure and outcome. For precision, typically a 95 percent confidence interval is used for interpretation.

Probability of rain on monday is what is the probability of no rain on Monday?
IF probability of rain is X percent then probability of no rain is 100- X percent. For example if prob of rain is 80% prob of no rain is 20%
Is a 95 percent confidence interval for a mean wider than a 99 percent confidence interval?
No, it is not. A 99% confidence interval would be wider. Best regards, NS
