at a school there are 10 students taking only chemistry, 9 students taking only physics 5 students taking both, and 16 students not taking either. if a student is randomly selected from the other school, what is the probability that they are taking chemistry or physics?

47.5%

Step-by-step explanation:

there are a total of 40 students.

19 of them are taking physics or chemistry.

so 19/40 are taking them.

19/40 = 0.475

which is 47.5%

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.

the function makes a strait line horizontally with no x intercept but a y intercept at 9.
