According to government data, the probability that a woman between the ages of 25 and 29 was never married is 40%. in a random survey of 10 women in this age group, what is the probability that two or fewer were never married
the probability of finding 2 never married 10c2*0.4^2*0.6^8= the probability of finding 1 never married 10C1*0.4*0.6^9= the probability of finding 0 never married 10C0*0.6^10=
the answer is all the above answers added together. think you can do the rest of the calculation by yourself. :)
