Electronics Unlimited sells TVs. There are 110 TVs on display in the showroom, and each TV is turned on to a random channel from
Lynna [10]

Answer:

  • <u><em>Option B. There will be close to 40 TVs but probably not exactly 40 TVs not showing a sports channel.</em></u>

Explanation:

There are a total of <em>7 sports channels</em> and 4 non-sports channels o<em>ut of 11 channels.</em>

The probability that one <em>TV will be not be showing a sports channel</em>, P(not S), is:

  • P(not S) = number of non-sports channels / number of channels.

  • P(not S) = 4/11.

The <em>best prediction</em> on <em>how many TVs will not be showing a sports channel </em>is, the expected value, which is equal to the number of TVs mulitplied by P(not S):

  • P(not S) = 110 × 4/11 = 40.

Since this is a random variable, the expected value is not the exact number of TV but just a probability.

Hence, the answer is the option <em>B: There will be close to 40 TVs but probably not exactly 40 TVs not showing a sports channel.</em>
