Let the time taken to finish the test be x.
P(50 < x < 60) = P(x < 60) - P(x < 50) = P(z < (60 - 60)/10) - P(z < (50 - 60)/10) = P(z < 0) - P(z < -1) = P(z < 0) - (1 - P(z < 1)) = P(z < 0) + P(z < 1) - 1 = 0.5 + 0.8413 - 1 = 0.3413
The answer is c. you just have to look at the red line. you can tell that it is solid so you know that y has to also be equal to the value. Then you can see that it is shaded above the line so that means y is greater than the value. Then since the line is on -1 the answer has to be c, y is greater than or equal to negative 1.
