Question: Help with some math work please?

Two fair coins are flipped simultaneously. This process is repeated until at least one of the coins comes up heads. What is the probability that both coins come up heads on this last flip?

Answer: Since the probability of one head on one coin is 1/2, and this is the same for the other:
P(Coin A is Heads, Coin B is Heads) = (1/2)(1/2) = 1/4

This changes when you ask what is the probability of getting two heads on the nth flip, from k flips of the two coins. Are you asking this?

Question: Wondering if i can get accepted into Florida Schools?

here are my SAT AND ACT SCORES

ACT: 17
SAT: Reading – 450 Math-330 Writing- 390…. So i made an 1170 total?? I was wondering if this is good enough to get into UCF or FIU. I have a 2.6 GPA Im also a Florida Resident if that helps….

Answer: To be completely honest, it’s going to be really tough to get into either one of them. Residency for any school really doesn’t make much difference. These stats were on UFC’s website and although they’re just averages and not minimum requirements, it definitely helps in letting you know where you may stand:

FTIC Applications: 25,000
FTIC Admits: 11,000
FTIC Enrolled: 3,850
Average SAT: 1225
Average ACT: 27
Average H.S. GPA: 3.8

You’re SAT scores are a little low but seem ok (combined score is actually 780–they don’t count writing), but the ACT score / GPA is killing you. I barely got accepted into a few of schools with my composite score of 25 and GPA of 3.3 (I didn’t apply to any crazy prestigious schools or anything either) I don’t know if you’re just going into your senior year or what, but if it’s at all possible I would take the ACT again! Even if you could just get a few numbers higher (20-21 at the least) especially if these are schools you REALLY want to get into, you know?
In addition to that, an awesome entry essay would boost your application!

Same goes for FIU. I think they’d be a little easier to get into though.

ACT Composite
30-361.6%
24-2935.8%
18-2356.0%
12-176.5%
6-11 0.1%

These are more specific and although only a small percentage in your range are accepted, it’s still possible. Do you also see what I mean too when I say to take the ACT again? Look at the percentage of freshman in the 18-23 range.. that’s more than half the class! And all you’d need is one or two more added to your score.

SAT scores (25/75 percentile):
Critical Reading: 500 – 600
Math: 505 – 590
Combined: 1005 – 1190

These are the averages of the SAT for FIU. Obviously a bit tougher. If you get take the SAT again all you’d need is 100 points for both Math and Reading added on (although I would focus on Math because your Reading score is really close). I know re-taking important tests like these really SUCKS but as I said before, if these are schools you are seriously considering then it wouldn’t hurt. Let’s say you do worse by some chance then you can stick with your higher scores from previously.

I also want to mention for the SAT scores above–remember that those are the middle 25-75% of people with those scores, which means you still have a chance with what you have now if you honestly don’t feel like re-taking anything. I’m just taking it all into consideration. Also remember that they’ll take a look at your class rank when making their decision. Obviously the lower the # the better! (I was like 120/475 If I can remember, which is in the top 30% of my class or something.)

50% had h.s. GPA of 3.75 and higher
23% had h.s. GPA between 3.5 and 3.74
12% had h.s. GPA between 3.25 and 3.49
11% had h.s. GPA between 3.0 and 3.24
4% had h.s. GPA between 2.5 and 2.99

Once again your GPA can still get you in but they’re going to want higher testing scores.

Haha, sorry I didn’t realize I wrote so much. Hope it helps though!
& Good luck
