Question

Dalia owns a gravel pit. She took a random sample of rocks and counted 585858 sedimentary rocks, 213213213 metamorphic rocks, and 522522522 igneous rocks.

Answer 1

Answer:

Sedimentary:0.07

Metamorphic:0.27

Igneous: 0.66  

Step-by-step explanation:

If this is of probability

first see the total rocks Dalia has

$58+213+522=793$

so the probability of sedimentary rocks is $\frac{58}{793}$

=0.07

probability of sedimentary rocks is $\frac{213}{793}$

=0.27

probability of sedimentary rocks is$\frac{522}{793}$

=0.66
