step One

Find the total number of rocks in the gravel pit

<em>58 + 213 + 522 = 793</em>

Step Two 

<em>Set up the probabilities.</em>

<em>P(Sedimentary) = 58 / 793 = 0.0731</em>

<em>P(metamorphic) = 213/ 793 =0.2686</em>

<em>P(igneous) =        522 / 793 = 0.6583</em>

Check

<em>When these are added together the answer should be one.</em>

<em>0.0731 + 0.2686 + 0.6583 = 1 just as it should.</em>
