Answer:
-40
You start at -5 then you add 20 to get 15 . Then you subtract 25 from 15 to get -10. Then you add 40 to -10 to get 30. Then you have to subtract 70 from 30 to get -40 F.

Answer:
P = 9/16
Step-by-step explanation:
In this question, we are asked to calculate the probability of Mrs Cox picking marbles that are not orange in color.
First, since we are dealing with the color orange and the rest according to the question, we can say that we have only two sets of marbles. The first set is the orange and that contains just 3 orange marbles. The second set contains 5 blue and 4 red marbles making a total of 9.
The probability of not selecting an orange is this; number of non orange marbles/total number of marbles
Total number of marbles is 12. The probability is thus 9/12 or3/4.
Now the probability of selecting a non orange marble twice without replacement is 3/4 * 3/4 = 9/16
