Leave out those who went less than twice to get those who went at least twice 
pr = (700 - 205)/700 = 0.7071 <-------

So answer is B

Answer:

B. 0.707

Step-by-step explanation:

The frequency table is given by,

Number of months                         Number of movie goers

     More than 7                                                96                  

           5 - 7                                                      180

           2 - 4                                                      219

      Less than 2                                               205

           Total                                                     700

Since, Probability of an event is the ratio of favorable events to the total number of events.

As, the number of people going to movies atleast 2 times a month = 96 + 180 + 219 = 495

The probability that a person goes to the movies atleast 2 times a month = [tex]\frac{495}{700}=0.707[/tex].

Thus, option B is correct.
