Answer:

P(At\ least\ 2) = 0.75

Step-by-step explanation:

Given

Balls = 1 to 4

Required

Determine the probability of selecting ball numbered at least 2

Here, we'll assume that all numbers have the same probability.

The probability of each ball will be:

Probability = \frac{1}{4}

So:

P(At\ least\ 2) = P(2) + P(3) + P(4)

Recall that

Probability = \frac{1}{4} --- for each ball

So, the equation becomes

P(At\ least\ 2) = \frac{1}{4} + \frac{1}{4} + \frac{1}{4}

P(At\ least\ 2) = \frac{3}{4}

P(At\ least\ 2) = 0.75

Let's turn this sentence into an equation:

8n = -n + 36

Then solve:

9n = 36 => n=4

lesya [120]
Since Y is the centroid then the larger piece of the median is 2 times that of the smaller piece

10 = 2*(2x - 3)

10 = 4x - 6

16 = 4x

x = 4

There are different levels of measurement that have been classified into four categories. It is important for the researcher to understand the different levels of measurement, as these levels of measurement play a part in determining the arithmetic and the statistical operations that are carried out on the data.

In ascending order of precision, the four different levels of measurement are:
