There are 4 green balls, 3 purple balls, 2 orange balls and 1 white ball in a box. one ball is randomly drawn and replaced, and then another ball is drawn. what is the probability of getting a green ball then an orange ball? 4/45 3/50 2/25 3/5

=2/25

Step-by-step explanation:

4/10*2/10

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

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
