Answer:

Step-by-step explanation:
Let M denote the event that the stock makes money and D denote the event that the stock pays dividends.
It is given that 
Observe that the two events M and D are not independent because if the stock doesn't make money then it will not pay dividends. Therefore the event  (D given M does not occur) is a null event, i.e
 (D given M does not occur) is a null event, i.e
 
 
It is also given that, 

Recall that : 
Here, we are required to find 

 
        
             
        
        
        
Answer:
The total number of pencils is 6
Step-by-step explanation:
According to the given scenario, the computation of the total number of pencils is as follows:
There are 18 students 
And let us assume there is m mechanical pencils that put in each bag
also he put twice of the regular pencil
So if he put the 3 mechanical pencil 
So, the total number of pencils is 
= 3 × 2 
= 6
As it twice of the regular pencil
hence, the  total number of pencils is 6
 
        
             
        
        
        
Answer:
Radius= 2r
Step-by-step explanation:
Surface area of hemisphere
=2 x 22/7 x (2r)^2
=44/7 x 4 r^2
=174/7 r^2
=25.14 r^2
