An urn contains balls numbered 1 through 20. A ball is chosen, returned to the urn, and a second ball is chosen. What is the pro
stira [4]
<h2>Answer:</h2>

The probability is:

                   \dfrac{1}{400}

<h2>Step-by-step explanation:</h2>

It is given that:

An urn contains balls numbered 1 through 20.

A ball is chosen, returned to the urn, and a second ball is chosen.

This means that this is a case of a replacement.

Hence, one of the event is independent of the other.

Now we know that the probability to get a particular number of ball is:

                  \dfrac{1}{20}

( Since, there are total 20 balls and a ball of one particular number is just unique )

i.e. \text{Probability of getting a 8}=\dfrac{1}{20}

Hence, the probability that the first and second balls will be a 8 is:

=\dfrac{1}{20}\times \dfrac{1}{20}\\\\\\=\dfrac{1}{400}

Answer:

\frac{5}{12} =\frac{2}{x}

Step-by-step explanation:

EF and JK are similar, and the other side we know, FG, is similar to KL. From there, just put them into a ratio!

\frac{EF}{JK} =\frac{FG}{KL}

\frac{5}{12} =\frac{2}{x}
