Step-by-step explanation:

Number 1

Step 1

The fundamental counting theorem states that for  process that can be carried out in k steps where the fist step can be done in   ways, step 2 can be done in  number of ways and the   can be done in number of ways, the number of ways to complete this task is ways.

Step 2

We now realize that this process can be carried out in 2 steps , there are 8 ways to complete the first step and 5 ways to complete the second step. The number of ways to carry out this calculation is shown below,

The correct answer is D.

Number 2

Step 1

in this step we calculate the number total number of cans in the ice chest.  Since there are 30 red cans and 20 green cans, there is a total of 50 cans.

Step 2

In this step we find the probability of grabbing a green can by dividing the total number of green cans by the total number of cans. The calculation for the probability is shown below,

The correct answer is D.

Number 3

Step 1

The first step is to realize that  there is a chance of getting a head when flipping a coin. When a die is rolled the sample space is {1,2,3,4,5,6}. From this we can tell that there are 3 out of 6 ways to get an even number from this sample space. The probability for an even number is

Step 2

The second step in this process  is to realize that these two events are independent hence we multiply the individual probabilities of the different outcomes to get the odds of a head and an even number. This calculation is shown below,

The correct answer is D

Number 4

Step 1

The first step is to realize that  the only unique letters in  INNOVATIVE  are {I,N,O,V,A,T,E}, i.e there are only seven unique permutations of these letters.

Step 2

The second step is to calculate the number of 4 permutations of 7 objects.

This is calculated as shown below,

There are 210 unique permutations of these letters.

Number 5

Step 1

Realize that the number of r combinations of n objects is ,

Step 2

We realize that in this problem we have to make 3 combinations of 11 objects. The calculation to determine the number of combination sis shown below,

Number 6

Step 1

We list the outcomes where we first get a head. These outcomes are {HH,HT}. Next we list the outcomes in which we get a tail first. These outcomes are {TH,TT }

Step 2

In this step we combine all the outcomes step 1. The combined list of outcomes is {HH,HT, TH, TT}

step-by-step explanation:

strong negative correlation

answer: yes, since the line has a steeper rate of change than the exponential the y-values will be greater and they will only intersect one time.
