a bag contains 9 marbles: 2 are green, 2 are red, and 5 are blue. justin chooses a marble at
random, and without putting it back, chooses another one at random. what is the probability that the first marble is green and the second is red?

the first draw will be 2/18 the second one will be 2/17

d (5 x (-20)) * (100 x (0.7))

step-by-step explanation:

5÷1/100 * -.7 *-20

copy dot flip

5*100 * -.7 *-20

rearrange

5*-20   * 100 *-.7

-100   *-70

7000

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.
