Given that <span>the weights of farmer carl's potatoes are normally distributed with a mean of 8.0 ounces and a standard deviation of 1.1 ounces.

The probability of a normally distributed data between two values (a, b) is given by:

$P(a\ \textless \ X\ \textless \ b)=P\left(z\ \textless \ \frac{b-\mu}{\sigma/\sqrt{n}} \right)-P\left(z\ \textless \ \frac{a-\mu}{\sigma/\sqrt{n}} \right) \\ \\ =P(7.5\ \textless \ X\ \textless \ 8.5)=P\left(z\ \textless \ \frac{8.5-8.0}{1.1/\sqrt{6}} \right)-P\left(z\ \textless \ \frac{7.5-8.0}{1.1/\sqrt{6}} \right) \\ \\ =P(z\ \textless \ 1.113)-P(-1.113)=0.8672-0.1328=0.7344$ </span>

What are the steps to find the solution to an inequality?

kifflom [539]

Answer:

Very similar to solving an equation.

Step-by-step explanation:

You have to use the properties of equality to "undo" each number and isolate the letter to one side.

How ever, if you are multiplying or dividing by a negative number, then the inequality must be reversed.

E and F are two events and that P(E)=0.2 and P(F/E)=0.6 what is P(E and F)

AVprozaik [17]

The probability of E and F expressed as P(E and F) equals;0.12

<h3>How to solve Conditional Probability?</h3>

We are given;

P(E) = 0.2

P(F|E) = 0.6

Now, P(F/E) is known as conditional probability and it means the probability of event F given the probability of another event E. This can be expressed as; P(F|E) = P(E and F)/P(E)

Thus;

P(E and F) = 0.2 * 0.6

P(E and F) = 0.12
