A sociologist randomly selects single adults for different groups of three, and the random variable x is the number in the group

Bas_tet [7]

Answer:

This data is not a probability distribution

The reason sum of the probabilities is not equal

∑ P(X=x) ≠ 1

Step-by-step explanation:

<u>Explanation</u>:-

Given data

x 0 1 2 3

p(x) 0.091 0.334 0.408 0.166

<u>Discrete distribution :-</u>

Probability distribution of a random variable is the set of its possible values together with their respective probabilities. Suppose X is a discrete random variable with possible outcomes (values) x₁ , x₂ , x₃ ,......... The probability of each possible outcome

$p_{i} = P(x=x_{i}) = p(x_{i}) for I= 1,2,3......$

If the numbers $p(x_{i}) , I =1 ,2,3,.....$ satisfy the two conditions

i) $p(x_{i}) \geq 0 for all values of i$

ii) ∑P(X=x) =1

Given data condition(i) satisfied $p(x_{i}) \geq 0 for all values of i$

but the condition (ii) is not satisfied

0.091+0.334+ 0.408+ 0.166 = 0.999

sum off all probabilities is not equal to one

<u>Conclusion</u>:-

The given data is not probability distribution

If the number of trials is 50. Then the probability that he will not roll a 3 on his next roll will be 0.20 or 20 %.

<h3>How to find that a given condition can be modeled by binomial distribution?</h3>

Binomial distributions consist of n independent Bernoulli trials.

Bernoulli trials are those trials that end up randomly either on success (with probability p) or on failures( with probability 1- p = q (say))

Suppose we have random variable X pertaining to a binomial distribution with parameters n and p, then it is written as

The probability that out of n trials, there'd be x successes is given by

P(X = x) = ⁿCₓ pˣ (1 - p)ⁿ ⁻ ˣ

Sawyer conducted an experiment in which he rolled a number cube 50 times. He rolled the number 3 a total of seven times.

Then the probability that he will not roll a 3 on his next roll will be

p = 1/6 = 0.1667

q = 1 - p = 1 - 1/6 = 0.8333

Then the probability will be

P = ⁵⁰C₇ (0.8333)⁴¹ (0.1667)⁷

P = 0.20
