The question requires that we calculate the theoretical probability of landing on the head.
This means that, we have to ignore the given data, and we use the following
 --- sample space
 --- sample space
 --- sample size
 --- sample size
 --- occurrence of Head
 --- occurrence of Head
So, the theoretical probability is:



 
        
             
        
        
        
Given:
Triangle 
height 14 inches
area 245 inches square
Formula in finding the area of a triangle is:
Area = (height * base) / 2
The base is missing, so we need to compute its value using the given figures.
245 = (14 * b) / 2
245 * 2 = 14b
490 = 14b
490/14 = b
35 = b
The base is 35 inches.
        
             
        
        
        
It will take 40 hours for the water tank to become empty.
Explanation:
Divide 30 by 0.75 (equivalent to 3/4).
