Answer: 
Step-by-step explanation:
Here the total numbers are 1,  4,  3,  7,  6
Since the total number of possible arrangement =  
 
The total number of the odd numbers in the given numbers = 3
Thus the possible arrangement that the first three digits will be odd numbers = 
Thus, the probability that the first three digits of Irvings ID number will be odd numbers = the possible arrangement that the first three digits will be odd numbers / total possible arrangement =   
 
= 
 
        
             
        
        
        
Area of the circle outside 
= πr2
= π(5)2 
=25 π
Area of the bigger circle inside 
= π x(3)2 
= 9 π
Area of the smaller circle inside 
= π x (2)2 
= 4 π 
Area of shaded region 
= 25π - 9π - 4π
= 12π square unit
        
             
        
        
        
Answer:
Example: A four-sided shape has two adjacent sides with lengths of 4 meters. You can find the area of this square by multiplying its base times its height: 4 × 4 = 16 square meters. Example: A square's diagonals are both equal to 10 centimeters.
