Recall that a probability is the likelihood of something occurring.

Mathematically, we can write probability as the following:

For this question, we want a red marble. Since there arered marbles, we havewanted outcomes. Since there is a total ofmarbles, we have a total ofpossible outcomes.

The probability then becomes the following:

Recall that a probability is the likelihood of something occurring.

Mathematically, we can write probability as the following:

For this question, we want a blue marble. Since there areblue marbles, we havewanted outcomes. Since there is a total ofmarbles, we have a total ofpossible outcomes.

The probability then becomes the following:

Recall that a probability is the likelihood of something occurring.

Mathematically, we can write probability as the following:

For this question, we want a green marble. Since there aregreen marbles, we havewanted outcomes. Since there is a total ofmarbles, we have a total ofpossible outcomes.

The probability then becomes the following:

Recall that a probability is the likelihood of something occurring.

Mathematically, we can write probability as the following:

For this question, we do not want a blue marble. This means that we are trying to find the proability of drawing either a red or a green marble. Since we havered marbles andgreen marbles, we havewanted outcomes. Since there is a total ofmarbles, we have a total ofpossible outcomes.

The probability then becomes the following:

Recall that a probability is the likelihood of something occurring.

Mathematically, we can write probability as the following:

For this question, we do not want a green marble. This means that we are trying to find the proability of drawing either a blue or a green marble. Since we haveblue marbles andred marbles, we havewanted outcomes. Since there is a total ofmarbles, we have a total ofpossible outcomes.

The probability then becomes the following:

Recall that a probability is the likelihood of something occurring.

Mathematically, we can write probability as the following:

First, write down the possible wanted outcomes:

Now, because there areeven numbers, we havewanted outcomes.

Since we are choosing numbers betweenand, inclusive, we have atotal outcomes.

The probability then can be written as the following:

Recall that a probability is the likelihood of something occurring.

Mathematically, we can write probability as the following:

First, write down the possible wanted outcomes:

Now, because there arenumbers divisible by four, we havewanted outcomes.

Since we are choosing numbers betweenand, inclusive, we have atotal outcomes.

The probability then can be written as the following:

Recall that a probability is the likelihood of something occurring.

Mathematically, we can write probability as the following:

First, write down the possible wanted outcomes:

Now, because there arenumbers that fit the criteria, we havewanted outcomes.

Since we are choosing numbers betweenand, inclusive, we have atotal outcomes.

The probability then can be written as the following:

The probability of an event not happening is one minus the probability it does happen.

Since the probability of winning the game is, then the probability of not winning would be,

.

To the probability of selecting a particular fish is the number of that fish divided by the total possible fish to choose from.

The total isgold fish plusbeta fish or.

So the probability of selecting a beta fish is
