The mathematics department of a college has 15 male professors, 11 female professors, 10 male teaching assistants, and 5 female teaching assistants. if a person is selected at random from the group, find the probability that the selected person is a teaching assistant or a female.

The answer is 26/41, or 63.4%

The number of people that fit into the Female or TA group is 26
This is because there are 16 total females, and 10 male TAs
Although there are 5 female TAs as well, they are already included in the 16 person female group, so they are not counted again.

Where m is the slope of the line and b is the y-intercept of the line, or the y-coordinate of the point at which the line crosses the y-axis. to write an equation in slope-intercept form, given a graph of that equation, pick two points on the line and use them to find the slope. this is the value of m in the equation.
