<h2>Okay, I got this packet and apparently it's a form of SAT prep. However, I don't know *** they're asking for. Can anyone help?</h2>

<p>-A computer was programmed to randomly generate numbers between 1 and 1,000. Martin kept track of the first 200 numbers that were generated. Jovi kept track of the second 200 numbers that were generated. Their results are shown below: </p>

<p>Martin Odd=106
Even=94</p>

<p>Jovi Odd=121
Even 74</p>

<p>a) Calculate as a percent the theoretical probability that the computer will generate an odd number.</p>

<p>b) From the data, calculate as a percent the experimental probability of the computer generating an odd number.</p>

<p>I didn’t even read the question. Confirm if it comes from Collegeboard. If yes then do it. If not and you still can’t figure out what the heck it’s asking, discard it- only a piece of crap</p>

3

<p>If it comes from a large company like Barron<code>s,Princeton review or Gruber</code>s ,I dont think he should discard it</p>

4

<p>It doesn’t come from collegeboard, it’s from this stupid revision workbook aimed at polishing my rusty math knowledge for the SAT.</p>

<p>bump bump :(</p>

<p>a) obviously have of the numbers are even, and half are odd. Thus the theoretical probability = 50%</p>

<p>b) 121 + 106 = 227 ; 227/400 = 56.8% or 56.75%</p>

7

<p>^Correct. Except I think that the question was either written incorrectly or copied down incorrectly. Jodi only counts 195 numbers in the OP.</p>

8

<p>^ I noticed that too. I figured 79 was correct.</p>
