Answer:
7.2 Kilometers
Step-by-step explanation:
800 meters = 0.8 kilometers
<u>Therefore, do 0.8 x 9</u>
0.8 x 9 = 7.2 kilometers
 
        
             
        
        
        
2/3 ÷ 4 = 2/3 * 1/4 = 2/12 = 1/6
        
                    
             
        
        
        
Answer:

And using the probability mass function we got:
 
  
Step-by-step explanation:
Let X the random variable of interest, on this case we now that:  
 
  
The probability mass function for the Binomial distribution is given as:  
 
  
Where (nCx) means combinatory and it's given by this formula:  
 
  
And we want to find the following probability:

And using the probability mass function we got:
