</p>

<p>you’re correct, I did the same thing</p>

22

<p>If this isn’t from the Blue Book, I have my doubts that questions similar to this will even be on the SAT</p>

23

<p>this wouldn’t be on the SAT, because it doesn’t say whether the probabilities were independent of each other.</p>

24

<p>well then, I don’t care about this then… This seems like an AP Stat problem or something. I’m only a sophomore, so I don’t know.</p>

25

<p>This is not an AP stat problem, maybe Algebra 2 or Analysis. This is actually very easy. </p>

<p>A question like this could be on an SAT, however this particular question is a bit ambiguous due to poor wording.</p>

26

<p>oh nvm i got it!! =D
BuddyMcAwesome is right and crazybandit, he just put it in a different way…
the probability of an event happening is 1 - probability of event not happening
or the probability of getting into a college = 1 - prob of not getting into any college
or = 1 - (.98<em>.86</em>.94*.95…etc.) which is about .634? or like antonioray said, 64%
=D</p>

<p>

</p>

<p>Isn’t the OP just trying to calculate his own chance of getting into college but wording it as a SAT problem for fun? =p</p>

28

<p>

</p>

<p>lol yea</p>

<p>sorry for the poor wording
how is it poorly worded again? for future reference?</p>

<p>and thanks again to buddy</p>

<p>also buddy, how would u modify the formula to find the chances of getting into at least 2 of the 13? at least 3? and so on</p>

<p>thanks</p>

<p>It’s poorly worded because it doesn’t say whether or not the chances are independent of each other.</p>
