For a binomial distribution, the mean is 0.6 and n = 2. What is π for this distribution?
Solution:
When the total probability (which is 1) is distributed among the different values associated with the random variable, we are distributing probability. Hence, it is called a probability distribution.
If there is a rule that determines what probability should be assigned to which value, then such a rule is called the probability distribution function.
The binomial distribution gets its name because the rule that determines the different probabilities are the terms of the binomial expansion.
The binomial distribution has its notation as B(n,π) where n denotes the number of trials and π represents the success probability for each of the trials.
Given, mean = 0.6
No of trials, n = 2
Mean = nπ
π = probability
0.6 = 2π
π = 0.6/2
π = 0.3
Therefore, the value of π is 0.3
For a binomial distribution, the mean is 0.6 and n = 2. What is π for this distribution?
Summary:
For binomial distribution, the mean is 0.6 and n = 2. The value of π for this distribution is 0.3
