It is the binomial type probability distribution.


The number of trial n= 7; the probability of the success trial is  0.265,  and the number of success trial k = 4. 


    P = C%5B7%5D%5E4%2A0.265%5E4%2A%281-0.265%29%5E3 = %28%287%2A6%2A5%29%2F%281%2A2%2A3%29%29%2A0.265%5E4%2A0.735%5E3 = 0.0685 = 6.85% (rounded).     ANSWER
