In a study to determine frequency and
dependency of cell-phone usage relative to
students in Grade 11 and Grade 12, there
were 285 students
chosen at random, and
the following results were recorded. What is the probability that a student who does not have a cell phone is from grade 11?

Respuesta :

Using it's concept, it is found that there is a 0.6 = 60% probability that a student who does not have a cell phone is from grade 11.

What is a probability?

A probability is given by the number of desired outcomes divided by the number of total outcomes.

Researching the problem on the internet, it is found that there are 30 students with no cell phones, and of those, 18 are in grade 11, hence the probability is given by:

p = 18/30 = 0.6.

0.6 = 60% probability that a student who does not have a cell phone is from grade 11.
