You have a container with balls numbered between 1 and 20, if you randomly draw a ball from the container, what is the probability that the number on the ball will be divisible by 4 or will have a value three through 9?

3 / 5

Step-by-step explanation:

Numbers divisible by 4: {4, 8, 12, 16, 20}

Values 3 through 9: {3, 4, 5, 6, 7, 8, 9}

In probability "or" means addition (+)

Therefore:

Prob. (no divisible by 4 or value 3 through 9) =

5 / 20 + 7 / 20

= 5 + 7 / 20

= 12 / 20

= 3 / 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.
