# Math Help - Find probabilities using F distribution tables

1. ## Find probabilities using F distribution tables

I need to find the answer to x~F (11,10) and P(X<or equal to2.94)... How do we use the table? How do we kow what percent critical values should we look into?

$P\left(x\leq 2.94\left|\nu _1\right.=11,\nu _2=10\right)=0.94985$

Thank you so much but how?

Tell me the one for X~F(16,75) P (X>and equal to 2.89)
Do we use the F tables? how?

$1-P\left(x<2.892\left|\nu _1\right.=16,\nu _2=75\right)=0.0029857$
