The probability which is most likely to occur is (1/2) which is equal to 0.50 or 50%.

What is Probability?

The probability helps us to know the chances of an event occurring.

$\rm{Probability=\dfrac{Favorable \ Outcomes}{Total\ Number\ of\ outcomes\ possible}$

1. How many favorable outcomes are expressed in the probability 7/9 ?

As the probability is been given to us comparing it with the formula of probability, the number of favorable outcomes is 7.

Thus, the number of favorable outcomes in the probability 7/9 is 7.

2. How many possible outcomes are expressed in the probability 14/25?

As the probability is been given to us comparing it with the formula of probability, the number of favorable outcomes is 14.

Thus, the number of favorable outcomes in the probability 14/25 is 14.

3. What fraction correctly shows the probability of 14 favorable outcomes out of 21 possible outcomes?

As we have already discussed the formula of probability, therefore, substitute the value in the formula of probability.

$\rm{Probability=\dfrac{Favorable \ Outcomes}{Total\ Number\ of\ outcomes\ possible}$

$\rm{Probability=\dfrac{14}{21} = \dfrac{2}{3}$

Which probability is least likely; 17/35, 5/13, 132/425, 1/2?

To know the probability which is most likely to occur we will convert all the given probabilities to decimal form,

17/35 = 0.4857

5/13 = 0.3846

132/425 = 0.3105

1/2 = 0.5

Hence, the probability which is most likely to occur is (1/2) which is equal to 0.50 or 50%.

1. 7

2. 25

3. 2/3

4. 132/425

Step-by-step explanation:

Probability is the likelihood of an event occurring and it can be computed by:

$Probability=\dfrac{favorable\hspace{1mm}outcomes}{all\hspace{1mm}possible\hspace{1mm}outcomes}$

1. So when you are given a probability of 7/9:

$Probability=\dfrac{favorable\hspace{1mm}outcomes}{all\hspace{1mm}possible\hspace{1mm}outcomes}=\dfrac{7}{9}$

So the answer is 7.

2. Given the probability is 14/25:

$Probability=\dfrac{favorable\hspace{1mm}outcomes}{all\hspace{1mm}possible\hspace{1mm}outcomes}=\dfrac{14}{25}$

The number of possible outcomes is 25.

3. You have 14 favorable outcomes out of 21 possible outcomes.

$Probability=\dfrac{favorable\hspace{1mm}outcomes}{all\hspace{1mm}possible\hspace{1mm}outcomes}=\dfrac{14}{21}\div \dfrac{7}{7}=\dfrac{2}{3}$

The answer is 2/3.

The least likely even would be the smallest fraction. If you want to do this the easy way, just change them all to decimal and find the value with the least.

17/35 = 0.49

5/13 = 0.38

132/425 = 0.31

1/2 = 0.5

Since 132/425 = 0.31 is the smallest, then it is the least likely probability.
