The required probability for P(x<92) is 0.15866.

Given that,
Sample score = X = 92
Mean = μ = 98
Standard deviation = σ = 6
p(x ≤ 92 ) is to be determined

<h3>What is probability?</h3>

Probability can be defined as the ratio of favorable outcomes to the total number of events.

z = (X - μ) / σ
z = (92 - 98) / 6
z = - 1

Now
Probability,
p(x < 92) = P(z = -1)
p(x < 92) = 0.15866 (from z score table)

Thus, The required probability for P(x<92) is 0.15866.

Answer:

$\angle CFD =105^o$

Step-by-step explanation:

Given

$\angle D FE = \angle DE F = 75^o$

See attachment

Required

Determine the measure of $\angle CFD$

$\angle CFD$ and $\angle DFE$ are on a straight line.

So:

$\angle CFD + \angle DFE = 180^o$ --- angle on a straight line

Substitute known values

$\angle CFD + 75^o = 180^o$

Collect like terms

$\angle CFD =- 75^o + 180^o$

$\angle CFD =105^o$

Answer:

$P (2) =\frac{1}{7}$ Theoretical probability

Step-by-step explanation:

The theoretical probability is defined as:

$P = \frac{number\ of\ desired\ results}{number\ of\ possible\ results}$

In this case we look for the probability of taking a 2 out of the bag. As there is only one paper with the number 2 in the bag then:

number of desired results = 1

The amount of paper in the bag is equal to 7, so:

number of possible results = 7

Thus:

$P (2) =\frac{1}{7}$

This is a theoretical probability, since we do not need to perform the experiment to calculate the probability.

To calculate the experimental probability we must perform the following experiment:

Take a paper out of the bag, record the number obtained and then return the paper to the bag.

Now repeat this experiment n times. (Perform n trials)

So:

$P (2) = \frac{number\ of\ times\ you\ obtained\ the\ number\ 2}{number\ of\ trials\ performed}$

To calculate a theoretical probability you always need to perform an experiment with n trials.
