Sample Response: The two conditional probabilities are not equal because each has different given events. P(A|D) has event D as
Ivan

The conditional probability illustrates that's there's a 2/8 that the event A occurs.

<h3>How to illustrate the probability?</h3>

It should be noted that probability simply means the likelihood of the occurence of an event.

In this case, it can be delivered that P(AID) and P(DIA) aren't equal.

Hence, P(D|A) has event A as its given event, resulting in 2/8 for a probability.

There are some people in a cinema.
Elan Coil [88]

Answer:

Adults = 510

Step-by-step explanation:

Given

Children = \frac{3}{5}

Girls:Boys = 2 : 7

Girls = 170

Required

Determine the number of adults

First, we need to calculate the number of children

Girls:Boys = 2 : 7

Given that: Girls = 170

Substitute 170 for Girls in Girls:Boys = 2 : 7

170 : Boys = 2 : 7

Convert to fraction

\frac{170}{Boys} = \frac{2}{7}

Cross Multiply

Boys * 2 = 170 * 7

Divide both sides by 2

Boys = \frac{170 * 7}{2}

Boys = \frac{1190}{2}

Boys = 595

So, the number of children are:

Children = Boys + Girls

Children = 595 + 170

Children = 765

Next, we calculate the number of people in the cinema.

Children = \frac{3}{5} * People

Substitute 765 for Children

765 = \frac{3}{5} * People

Make People the subject.

People = \frac{765 * 5}{3}

People = \frac{3825}{3}

People = 1275

If 3/5 are children, then 2/5 are adults.

So:

Adults = \frac{2}{5} * 1275

Adults = \frac{2* 1275}{5}

Adults = \frac{2550}{5}

Adults = 510

I need a number greater than 25 that has more factors than 19,21,23
Free_Kalibri [48]
19 has two factors: 1, 19
21 has four factors: 1, 3, 7, 21
23 has two factors: 1, 23

And so we need a number that has more than four factors, and is greater than 25.

50 is one number that fits.

Factors of 50: 1, 2, 5, 10, 25, 50

50 has six factors and is greater than 25.

Hope that helped :)

It takes 0.5 gallon of cream to make 1 pound of butter. How much cream would you need to make 2.5 pounds of butter?
Natasha_Volkova [10]
1.25 gallons


so we know 0.5 gallons makes 1 pound, and we know that there are at least 2 pounds of butter made.


so we know that there is 1 full gallon of cream used.


however, there is also .5 pounds of butter, so we need to find out the other half.



to do this, we need to split the .5 gallons of cream in half, making 0.25



then, we add 1 + 0.25 gallons to equal 1.25 gallons of cream needed to make 2.5 pounds of butter
