Answer:
The probability a person selected random is not suffering from Malaria  is 0.725.
Step-by-step explanation:
Denote the events as follows:
X = a person is suffering from Malaria
M = a man 
W = a woman
The information provided is:
P (M) = P (W) = 0.50
P (X|M) = 0.10
P (X|W) = 0.45
Compute the probability a person selected random is suffering from Malaria as follows:

          
Then the probability a person selected random is not suffering from Malaria  is:
P (X') = 1 - P (X)
          = 1 - 0.275
          = 0.725
 
        
             
        
        
        
Answer:
2x^{4}
Step-by-step explanation:
You would subtract 7 and 5 and you would leave the exponent so it would be 2x^{4}
