The probability of scoring more than 90% on a certain end of year exam is 0.009. Given the events are independant, find the probability of two tests scoring more than 90%. Is it simply 0.009 x 0.009 = 0.000081?

No worries. I was making fun of the wording, not your attitude. Consult those defintions. They WILL save you!
