Suppose that the distribution of weights of ducks in farms in Bulacan is normally distributed with mean 1.4 kg and standard deviation of 0.12 kg. What is the probability that a randomly selected duck weighs more than 1.8 kg?

the probability that a randomly selected duck weighs more than 1.8 kg is 5-10%

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square
