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.

Probability of getting one volcano in the world on which to conduct an extensive study is

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

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

Hence, Probability of getting one volcano in the world on which to conduct an extensive study is

answer: y = -2.5x - 15

              (-6,0)
