~~~~~~~~~~~~~~~~~
In an encrypted form, it is a binomial distribution probability problem.
The number of trials is 7; the number of successful trials is k <= 3; the probability of success for each single individual trial is p = = 0.75.
Therefore, the formula to calculate the probability is
P(n=7; k<=3, p= 0.75) =
To facilitate my calculations, I used online calculator at this site https://stattrek.com/online-calculator/binomial.aspx
It provides nice instructions and a convenient input and output for all relevant options/cases.
The resulting number is P = 0.07055664063 = 0.0706 = 7.06% (rounded). ANSWER
