Can anyone help me with this? If Z ~ N(0,1) determine P(Z^3 > 1) I used the formula: x-miu/standard deviation where miu=0 and standard deviation is sq. root of 1. I tired: P(z^3>1) P((x-0/1)^3>1) P(x^3>1) P(x>1) I looked up the area of the standard normal distribution tables and...

Thanks! :)

Hi tiny-tim, Okay well my main problem is that I don't know what formula to use. I thought you would use p(q)^x-1 where p is the probability of success(0.5) and q is the probability of failing (0.5), x is supposed to be the number of trials ie the number of times the coin is tossed but...
