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

Sedimentary:0.07

Metamorphic:0.27

Igneous: 0.66

Explanation:

If this is of probability

first see the total rocks Dalia has

`58+213+522=793\\`

so the probability of sedimentary rocks is
`(58)/(793)`

=0.07

probability of sedimentary rocks is
`(213)/(793)`

=0.27

probability of sedimentary rocks is
`(522)/(793)`

=0.66
