Answer:
0.3285
Step-by-step explanation:
This problem involves Geometric probability distribution because experiment is repeated different number of times until success is achieved.
we have to find P(X≥4). It can be written as P(X≥4)=1-P(X<4)=1-P(X≤3)
P(X≤3)=?
Using Geometric probability distribution
P(X=n)=p^x*q^n-1
P(X≤3)=P(X=1)+P(X=2)+P(X=3)
Here p=0.31,
P(X≤3)=0.31^1*0.69^0+0.31^2*0.69^1+0.31^3*0.69^2)=0.6715
P(X≥4)=1-P(X≤3)=1-0.6715=0.3285
The probability that the first strawberry candy chosen from a bag will be, at LEAST, the fourth candy chosen overall is 32.85%.
Answer:
The point will have both a positive x value and a positive y value.
Step-by-step explanation:
<em>Since the question leads me to believe this is multiple choice but there are no choices provided, I will do my best to guess what it is wanting.</em>
The last one is always so. "People will elect Trump by a narrow margin based on a sample of 10000 people with a % error of 2%" is a typical statement.
A probability experiment will always count the number of times an event occurs. That's the whole point of an experimental probability. How many people respond favorably to a new Cancer Treatment is a typical question asked by someone conducting an experiment in probability.
C is kind of iffy. Perhaps it is too expensive, or it takes place over too long a period. Ideally repeat trials should take place whenever possible. Bone Marrow Transplants are very expensive because of the strict isolation conditions. You're likely only to get one study done this, especially initially. To check to see if Cancer is a generational thing would be an example of a study that takes too long to repeat many times.
B is simply not true. They are not the same. What theoretical model would you use to mimic a survey? You actually have to go do the survey.
A is wrong. It is the other way around.
Answer C is a maybe but check it. D and E are both true.
Answer:
68 is the perimeter
the answer would be 48.17
Step-by-step explanation:
to find the perimeter you have to add all the sides
