Answer:
See below and attached.
Step-by-step explanation:
Draw a rectangle.
Divide it in half.
Divide each part in half again.
Lastly, divide each part again in half.
This will give a total of 8 sections.
Project a uses 1/2 of the fabric. This means it will use 4 out of the 8 pieces.
Project b uses 1/4 of the fabric. This means it will use 2 out of 8 pieces.
So the fabric that is left is 1 - 1/2 - 1/4 = 1/4.
You can find the amount left for any number of yards of fabric by taking f(x) = x/8 - 3/4
Answer:
1. P(X=0)=0.135
2. P(T>1)=0.271
Step-by-step explanation:
1. Let X be the number of accidents in the next year. Find the distribution of X and calculate P(X=0).
The rigth distribution to describe this type of event as number of accidents per unit of time is the Poisson distribution.
In this case k=0 accidents, parameter λ=2 events/year and t=1 year:
2. Let T be the amount of time until the next accident. Find the distribution of T and calculate P(T>1).
In this case, the time between events can be best described by an exponential distribution:
In this case parameter λ=2 events/year and t=1 year:
