A bag contains 32 red blocks, 47 green blocks, 21 yellow blocks, and 25 purple blocks. You pick one block from the bag at random. Find the indicated theoretical probability.
P(green or purple)

P(green or purple) = 0.576

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this problem, we have that:

32 + 47 + 21 + 25 = 125 blocks.

Of those, 47 + 25 = 72 are green of purple

P(green or purple) = 72/125 = 0.576

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.
