Answer:
Recall that probability is given as; the number of required outcome over the number of total possible outcome.
The probability that a transmitter receives the signal being sent by itself is given as .
when there are n transmitters, the probability will be given as
Step-by-step explanation:
Probability simply the likelihood of an event occurring or not occurring.
Probability therefore is given as; the number of required outcome over number of possible outcome.
In the case of the first part above we have the number of required outcome to be at least one divided by the number of possible outcome which is 3.
while in the second part we have the number o possible outcome to be n.
Answer:
97.7% of of the boxes weigh more than 22.9 ounces.
15.9% of of the boxes weigh less than 23.7 ounces.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 24.5 ounces
Standard Deviation, σ = 0.8 ounce
We are given that the distribution of boxes weight is a bell shaped distribution that is a normal distribution.
Formula:
a) P(boxes weigh more than 22.9 ounces)
P(x > 22.9)
Calculation the value from standard normal z table, we have,
97.7% of of the boxes weigh more than 22.9 ounces.
b) P(boxes weigh less than 23.7 ounces)
P(x < 23.7)
Calculation the value from standard normal z table, we have,
15.9% of of the boxes weigh less than 23.7 ounces.
