I'm a little confused on how you would do something like this:(adsbygoogle = window.adsbygoogle || []).push({});

I have a cumulative probability distribution H(x):

0 0.31042

1 0.67825

2 0.89149

3 0.97196

4 0.9942

5 0.999

6 0.99985

7 0.99997

8 1

and I need to find the 90th percentile of demand..

I understand that this means its the minimum x so that H(x) >= 90% but I need an example to make sure I'm doing this right.

Would this mean x >= 3 in this case??
