A bag contains 5 red marbles and 10 blue marbles. If Jen selects a marble from the bag without looking, what is the probability that she will not pull out a red marble?

since there is more blue marbles in the bag, she will have a higher chance of pulling out a blue marble instead of red, since there are less red marbles she has a lower chance of getting a red marble.

Step-by-step explanation:

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 correct answers i think are b. and d.

give me brainliest if it is correct!
