For a given a event what is the result of dividing the number of successful outcomes by the number of possible outcomes

galina1969 [7]

The number of successful outcomes can be represented by p while number of unsuccessful outcomes can be represented by q. In this case, the sum of p and q is equal to the sample space, regarded here as n. so, taking the quotient of the two:

p/q = p / n-q

If these were expressed in probabilities:
p/q = p / 1- p

The quotient would be greater than 1.

g Consider a brand of coffee. The weight of a pod of coffee this brand makes has mean 42.05 grams and standard deviation 0.025 g

Brums [2.3K]

Using the normal distribution, it is found that there is a 0.0013 = 0.13% probability that the mean weight of 25 pods of coffee is less than 42.035 grams.

<h3>Normal Probability Distribution</h3>

The z-score of a measure X of a normally distributed variable with mean $\mu$ and standard deviation $\sigma$ is given by:

$Z = \frac{X - \mu}{\sigma}$

The z-score measures how many standard deviations the measure is above or below the mean.

Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.

By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation $s = \frac{\sigma}{\sqrt{n}}$ .

The parameters are given as follows:

$\mu = 42.05, \sigma = 0.025, n = 25, s = \frac{0.025}{\sqrt{25}} = 0.005$

The probability that the mean weight of 25 pods of coffee is less than 42.035 grams is the <u>p-value of Z when X = 42.035</u>, hence:

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{42.035 - 42.05}{0.005}$

Z = -3

Z = -3 has a p-value of 0.0013.

0.0013 = 0.13% probability that the mean weight of 25 pods of coffee is less than 42.035 grams.
