Asurvey was done that asked people to indicate whether they preferred pool swimming or ocean swimming. the results of the survey are shown in the two-way table.

chantal is making a relative frequency table from this data.

what operation should chantal perform to determine the relative frequency of a person over 30 years old who prefers ocean swimming?

I am 100% sure it is A. I did the test and it showed it was A.

Please leave a thanks.

answer:

step-by-step explanation:

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
