X=7/3 and x=7/2
if you want the step-by-step then you just try to isolate x and it is pretty self-explanatory from there on. Hope this helped!
:P
Answer:
5
Step-by-step explanation:
distance formula √[(x1-x2)²+(y1-y2)²]
Answer:
a) P(X=x) = p× (1-p)^(x-1)
b) P(X=3) = 0.081
c) P(X≤5) = 0.40951
d) Mean of X= 10
e) Var(X)= 90
Step-by-step explanation:
This is a question on geometric distribution.
In geometric distribution, we have two possible outcomes for each trial (success or failure) for independent number of binomials series trial. Also the probability of success is constant for each trial.
This discrete probability distribution is represented by the probability density function: f(x) = p× (1-p)^(x-1)
For a random variable with a geometric distribution, we do not know the number of trials we will have = {1, 2, 3, ...}
We stop the trials when we get a success.
From the question, there are 10 numbers
The probability of success = p = 1/10
For the solutions of the question from (a-e), See attachment below.
f(x) = P(X= x)
Where P(X= x) is the probability of X taking on a value x
This is the best way to show you step by step. i love this website/app it’s called Math papa and you type in your problem and it helps you with the steps. this is how i got so good at math.
