The probabilities of getting n questions correct by guessing (p(correct) = 0.25):
n.....p (in %)...cumulative p (n or fewer questions correct by guessing)
0.....5.63.......5.63
1.....18.77......24.40
2.....28.16......52.56
3.....25.03......77.59
4.....14.60......92.19
5.....5.84.......98.03
6.....1.62.......99.65
7.....0.31.......99.96
8.....0.0369.....99.9969
9.....0.003......99.9999
10....0.0001.....100
Thus, if you guess 5 or more correctly you're doing really, really well. [img]graemlins/petard.gif[/img]
