Answer: Independent event
Step-by-step explanation:
When two events are independent of each other, this means that the probability that one event will occurs does not in any way affects the probability of the occurrence of the other event.
For example, card is picked at random from a deck of cards, and after putting it back,thne another card is picked at random. The probability of picking the cards is not affected by each other since it is put back.
 
        
             
        
        
        
You would do 0.25x (x is the unknown total number)=19. It is because of is a multiply sign, so 0.25*x=19. Divide both sides by 0.25 and you get 76 as your answer.
        
                    
             
        
        
        
The next step in the series will be Option B 
<h3>What is a Series ?</h3>
A series is the sequence of object in pattern.
From the given figure it can be seen that the red and blue colour semicircle are shifting alternately , and the number series is increasing by 1 
Therefore the next step is red on the right side , blue on the left side and no. 4 written on blue 
Therefore Option B is the right answer.

Width = X
Length = X + 15
Perimeter of a Rectangle = 2W + 2L
2(X) + 2(X + 15)
2X + 2X + 30
4X + 30
Answer = 4X + 30
Hope this helps! :)
