Answer: 0.0475

Step-by-step explanation:

Given :  A firm’s marketing manager believes that total sales X can be modeled using a normal distribution.

Where , Population mean : \mu=2.5\text{ million}=2.5\times1000000=2500000

Standard deviation : \sigma=300000

To find : Probability that the firm’s sales will exceed $3 million i.e. $ 3,000,000.

∵ z=\dfrac{x-\mu}{\sigma}

Then , for x= 3,000,000

z=\dfrac{3000000-2500000}{300000}=1.67

Then , the  probability that the firm’s sales will exceed $3 million is given by :-

P(z>1.67)=1-P(z

Hence, the probability that the firm’s sales will exceed $3 million = 0.0475
