ELEN [110]

Answer:

Step-by-step explanation:

We are given the following in the question:

Amount of time spent  listening to tapes of Beethoven and Brahms =

=\dfrac{3}{4}

Amount of time spent  listening to Beethoven =

=\dfrac{1}{5}

Total time spent listening to Brahms =

Amount of time spent  listening to tapes of Beethoven and Brahms - Amount of time spent  listening to Beethoven

=\dfrac{3}{4}-\dfrac{1}{5}\\\\=\dfrac{15-4}{20}\\\\=\dfrac{11}{20}\text{ Hours}\\\\=0.55\text{ Hours}

Answer:

\frac{1}{20}

Step-by-step explanation:

First, we need to look at the # of chips. There are a total of 25, 6 of which are blue.

This means that the chance of getting the first blue chip would be \frac{6}{25}

As there is no replacement, the total number of chips is 24 and there are only 5 blue left. This gives us the chance of \frac{5}{24}

Now all we need to do is mulitply these two and then simplify

\frac{6}{25} *\frac{5}{24} =\frac{30}{600} =\frac{1}{20}
