<u>2. What is P(M), the probability that a student plans to major in mathematics?</u>
- P(M) = number of students who plan to major in mathematics / number of students
Hope this can help you out some! :)
*There is a line under the greater than and less than sign is to show it can "greater than or equal to" or "less than or equal to"*
9 ≥ w and 2 ≤ w
*Since it says and, we solve both of them together.
If it said "OR", we would do the one side first then the other side*
9 ≥ w and 2 ≤ w
-2 -2
7 ≥ w and 0 ≤ w
Answer:
7 ≥ w and 0 ≤ w
