congrats, now post up your answers.vladimirv said:What was the answer to the very last question, 7 b iv)
I got something very small like 0.16, and something larger.
I managed to finish the test with about 25 min remaining, and checked my whole paper except for 7 b)
So far nothing wrong i think
i can't believe i wrote down the ranges for the last question instead of the widths.
*bangs head against the table.
