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

Answer:
171
Step-by-step explanation:
I divided 340 first and got 170 for each page number then I had 3 left over.

So the first page number should be 171 :)
I hope this helped you understand :)
