So we just divide 165 by 3.75 to get 44 copies per minute.

Hi!

So I would do this problem by dividing 165 copies by 3 minutes and 45 seconds; that's finding how many 3 minutes and 45 seconds go into 165, and results in how many copies are made in a minute.

Since 3 minutes and 45 seconds is in reality, 3 3/4 minutes, as there are 60 seconds in a minute, I would divide by 3 3/4, or 3.75.

165 / 3.75 = 44

So therefore, a copy machine makes 44 copies per minute.

Try to estimate the probability you'd turn on the radio and hear a song you were thinking about. In other words, estimate the pr

Probabilities are used to determine the likelihood of events

The value of the probability P(thinking of a song)P(turn on the radio and hear the song) is 0.056

<h3>How to estimate the probability</h3>

To calculate the probability, we make use of the following representations:

Event A represents the likelihood of thinking of a song
Event B represents the likelihood of turning on the radio and hearing the song

So, we have:

P(thinking of a song)P(turn on the radio and hear the song) = P(A) * P(B)

Assume that:

P(A) = 0.12 and P(B) = 0.47

So, we have:

P(thinking of a song)P(turn on the radio and hear the song) = 0.12* 0.47

Evaluate the product

P(thinking of a song)P(turn on the radio and hear the song) = 0.0564

Approximate

P(thinking of a song)P(turn on the radio and hear the song) = 0.056

Hence, the value of the probability P(thinking of a song)P(turn on the radio and hear the song) is 0.056
