We know that 3/10*20=6 students are eating salads.
We also know that 3/5*20=12 students are eating sandwiches.
Assuming each person only eats one thing, there are 20-12-6=2 students eating lunches other than salads or sandwiches.

9 * 44 =
9 (40 + 4) =
9(40) + 9(4) =
360 + 36 = 396
Answer:
The probability that the actual event is less than 6.5 inches is 0.9999.
Step-by-step explanation:
We are given that you have determined that for this gage you have a standard error of 30%.
For a precipitation event of 5 inches, we have to find the probability that the actual event is less than 6.5 inches.
The z-score probability distribution for the normal distribution is given by;
Z = ~ N(0,1)
where, = mean precipitation event = 5 inches
standard error = = 0.30
Now, the probability that the actual event is less than 6.5 inches is given by = P(X < 6.5 inches)
P(X < 6.5 inches) = P( < ) = P(Z < 5) = 0.9999
The above probability is calculated by looking at the value of x = 5 but in the z table the last value of x is given as 4.40 so we take the area of that value only which has an area of 0.9999.
