Re: Guys does anyone have the answers for the probability for the hsc. Here are the Q
i agree with the answers sghguos got.
ii) should be 26/35 not 27/35, its a 1 mark question should be an indicator that it is just a simple subtraction
when they say x = e^-2X for x=0.6 and x=0.7 ....................
You first have to rearrange to like ----> fx = e^-2x - x or fx = x - e^-2x
But how do you know which one to rearrange to? they both give different values if you sub x = 0.6 or 0.7
Heres another...
