Answer:
0.1587
Step-by-step explanation:
According to the situation, the solution and the data provided is as follows
mean = 12.45 ounces
Standard deviation = 0.30 ounces
maximum = 12.75 ounces
More than ounces of soda = 12.75
Based on the above information, the probability is

As we know that
P(Z<1) = 0.8413
So,
P (X > 12.75) = 1 - 0.8413
= 0.1587
20*65 = 1300
That's the price without tax.
Now to find tax:
1300*.035 = 45.5
1300+45.5 = $1345.5
$1345.5 is your total
Probabilities are used to determine the chances of an event.
The probability that the two bags are selected for extra screening is 0.02
The given parameters are:
--- number of bags
--- the probability that a bag is selected for extra screening
The probability that the two bags are selected for extra screening is:

So, we have:

Express percentage as decimal


Approximate

Hence, the required probability is 0.02
