Question 1169548: According to a recent study, 1 in every 7 women has been a victim of domestic abuse at some point in her life. Suppose we have randomly and independently sampled twenty-five women and asked each whether she has been a victim of domestic abuse at some point in her life. Find the probability that at least 2 of the women sampled have been the victim of domestic abuse. Round to six decimal places.

From the calculator
1-binomcdf(25,(1/7),1)=0.890468
probability of 0 is (6/7)^25=0.0212
probability of 1 is 0.0883
that adds to 0.1095
and 1-0.1095 is 0.8905, confirming the above answer.
