Which probability distribution table reflects the data shown in the bar graph?

First one :   The top left table

Second one : 

The total number of students =  95 + 105 + 145 + 220 = 565

% 7 - 9  =   95/565 =  .168

The top right table must be correct

Third one :

P(-1/3) < 0

Sum of probabilities = 2/3

Last one :

P( x = 2  or x = 0)  =  P(x = 2) + P( x = 0) - P(x=2 and x = 0)  =

0.1 + 0.3  - (0.1 * 0.3)  =

0.4 - .03 =

0.37
