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

Answer: Probability of getting one volcano in the world on which to conduct an extensive study is $\frac{1}{37}$

Step-by-step 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

$\frac{\text{Number of favourable outcomes}}{\text{Total number of outcomes}}\\\\=\frac{1}{37}$

Hence, Probability of getting one volcano in the world on which to conduct an extensive study is $\frac{1}{37}$

Answer 2

Answer: Cinder cone: 13/37

               Shield: 18/37

               Stratovolcano: 6/37
