Question

Using the table below, what is the probability that a student studies physics?

Answer 1

Pr(student studies physics, if chosen randomly) = total number studying physics divided by total number of students = 33/80

Answer 2

You can get that information just from the totals. Assuming all of the 6 boxes have equal probability, what you want specifically is the fraction in your data of all of the students that study physics.

To get that number, you need to figure out the total number of people (men and women) that study physics, and then figure out the total number of people in the survey. Both of those numbers are in the "total" section of your table. After that, you just divide the physics number by the total number, and then multiply by 100. That last step is the formula for calculating a percentage of your data, which is what I'm interpreting "probability" to mean in your question.

Hope this helps!
