Question

Eitan randomly selected volcanoes to travel to and study. After traveling, he had seen 13 cinder cone volcanoes, 18 shield volcanoes, and 6 stratovolcanoes.

Use the observed frequencies to create a probability model for Eitan randomly selecting one volcano in the world on which to conduct an extensive study.

Answer 1

cinder cones ) = 13/37

shield ) = 18/37

stratovolcanoes) = 6/37

Answer 2

Answer: Probability of getting one volcano in the world on which to conduct an extensive study is
`(1)/(37)`

Explanation:

Since we have given that

Number of cinder cone volcanoes = 13

Number of shield volcanoes = 18

Number of stratovolcanoes = 6

Total number of volcanoes is given by

`13+18+6\\\\=37`

So, Probability of selecting one volcano in the world on which to conduct an extensive study is given by

`\frac{\text{Number of favourable outcomes}}{\text{Total number of outcomes}}\\\\=(1)/(37)`

Hence, Probability of getting one volcano in the world on which to conduct an extensive study is
`(1)/(37)`
