What is the answer for this question
Ugo [173]

Answer:

1 - 1/10

Step-by-step explanation:

As strange as it may seem, the easiest way to answer this question is to calculate the probability of selecting an elephant first and then to subtract this probability from 1:

Adding up the Numbers of animals, we get 12+4+3+11, or 30.  The probability of selecting an elephant is thus 3/30, or 1/10.

Thus, the probability of NOT selecting an elephant is 1 - 1/10 (Answer A).

100 points and beainliest due yesterday
Sedbober [7]

Answer:

The relation is discrete function

Domain is  {x|x = 2,2,2}

Range is {y|y = 4, -1, -3}

Step-by-step explanation:

I. This function is discrete because x = 2,2,2

and y = 4, -1, -3

Or (2,4), (2,-1) and (2,-3)

If this function is continuous, the x and y will be something like this -3 <= x <= 3

II. Domain is x.value

III. Range is y.value

Ask me for anything.
