Answer:
9/25 
Step-by-step explanation:
Our denominator is the total amount in class. x/25
Our numerator is the total of people are "the probability that a student chosen at random has a cat and a dog"  Which is -9.
~~~Hope this helps~~~ :)
 
        
             
        
        
        
The possible digits are: 
5, 6, 7, 8 and 
9. Let's mark the case when the locker code begins with a prime number as 
A and the case when <span>the locker code is an odd number as 
B. We have 
5 different digits in total, 
2 of which are prime (
5 and 
7).
First propability:
</span>

<span>
By knowing that digits don't repeat we can say that code is an odd number in case it ends with 
5, 7 or 
9 (three of five digits).
Second probability:
</span>
 
 
        
        
        
Step-by-step explanation:
Consider the provided information.
For the proportion method first set up the equation like this:

Perform the cross multiplication and then solve for the missing part.
For example:
Find 80 percentage of 10.
Step 1: Set up the equation.


Step 2: Perform the cross multiplication

Step 3: Solve for the missing part.


 
        
                    
             
        
        
        
In a triangular prism, B usually stand for the triangular base of the prism. It is the area of the triangle.
Area of a right triangle = ab/2
a = long leg ; b = short leg
Given measures are:
a = 4 yd ; b = 3 yd
A = (4 yd * 3 yd)/2 = 12 yd² / 2 = 6 yd² is the value of B.
the hypotenuse is 5 yd but it is not needed to get the area of the right triangle base. 7 yd is the measure of the height of the triangular prism.
