Given Information:

Probability of success = 30%

Sample size = n = 3

Variable of interest = x = 2

Required Information:

Probability of exactly 2 graduates = ?

Answer:

Probability of exactly 2 graduates = P(2; 3, 0.30) = 0.189

Step-by-step explanation:

The given problem can be modeled as a binomial experiment since a random selected student can either b graduate or not therefore, there are only 2 outcomes. Each trial is independent and the probability of success is not changing from trial to trial. The number of trials in also fixed.

We know that a binomial distribution is given by

P(x; n, p) = nCx pˣ (1 - p)ⁿ⁻ˣ

Where p is the probability of success and 1 - p is the probability of failure, n is number of independent trials and x is the variable of interest.

For the given problem, we know that x = 2, n = 3 and p = 0.30

P(2; 3, 0.30) = 3C2*0.30²*(1 - 0.30)³⁻²

P(2; 3, 0.30) = 3*0.30²*(0.70)¹

P(2; 3, 0.30) = 0.189

Find and interpret the percentile for colorado which has 10.1

Lelechka [254]

The problem here is incomplete, but I found a problem online that must be the same to this. The picture is attached. The figure shown is a stemplot. The numbers to the left of the bar is the stem, while numbers to the right are the leaves. So, if you want to find 10.1%, find the row where the left number is 10. Then, find the corresponding 1 among the numbers to the right. That is 10.1% for the older folks living in Colorado.

1)
False, it represent range,
2)
False, It is a function
3)
True, c represent range
4)
x=20
C=20*20+5=405
It is a function, for amount we assigne one value.
