    Step-by-step explanation:

    Given : Jerry conducted a survey to determine the favorite flavor of ice cream in the seventh grade. he surveyed 40 students and found that 1 out of 4 students like vanilla ice cream the most.

    To Find: if a random 7th grader was chosen from Jerry's school what is the likelihood the student would like vanilla ice cream?

    Solution:

    Since we are given that 1 out of 4 students like vanilla ice cream the most.

    So, probability of liking vanilla is 1/4 = 0.25

    Now,

    Likely : When an event has a good chance of happening i. e. probability of event must be greater than 1/2 = 0.5

    Unlikely : When an event does not has a good chance of happening i. e. probability of event must be smaller than 1/2 = 0.5

    Certain : When an event will always happen i. e. probability must be 1

    Impossible : When an event will never happen i. e. probability must be 0

    Since probability of liking vanilla is 1/4 = 0.25 less than 0.5

    So, the likelihood is Unlikely according to definitions

    So, Unlikely is the likelihood the student would like vanilla ice cream
