How can I marry someone if I have been in this country for 10 years after my J1 Visa expired.?
The question is " How you can marry someone if you have been in this country for 10 years?"Now, i cannot understand clearly what do you mean. First, i assume that you do not have any legal status right now.Second, it is possible for you to marry and receive a green card if that was the original question. You have entered the USA legally through your J1 visa, due to that reason you will not be required to go back and re-enter USA legally again. The point is that you need a lawyer if you want to marry and apply for immigration status. If they approve your petion the immigration officer will grant you a pernament resident card , probably conditional.Now, i am not sure about another one possibility here. You might have a chance to apply for immigration status without marriage if you prove that you have lived in the USA in that period of time. Eventually, you have to pay some fine and taxes , but i believe this is another alternative. However, you definitely need a lawyer for your case. I had a friend who was here for 9 years illigaly and she got married with good lawyer , she received her green card in 6 months, so cheer up there are always possibilities.
Good luck!
If The first card is an ace and the second is also an ace what the probility?
Just a straight deal, the first card will be an ace 4 times out of 52, the second card will be an ace 3 times in 51. The total odds will be 12 times in 2652.
However in the question posed the first card is an ace so the probability is 1 in 1, so the second card being an ace will occur 3 times in 51.
In the question , the first card is ACE, and second is also an ACE. Hence probability is 1in 1.
How ever the question should be framed "What is the probabilty for getting first card An ACE and also Second card as An ACE"

36 possible outcomes, assuming replications (ie: rolling a 6 and a 1, rolling a 1 and a 6; counted as two separate outcomes.)
What are the major events that occur during childbirth?
Miracles
Normally labor, the birth of a baby and delivery of the placenta.
Complications include placenta abrupture, uterine rupture, maternal hemorrhage, prolapse cord, maternal or fetal death. These are all worst case scenarios and seldom happen to a healthy, well nourished woman in labor.
There are 4 numbers (7-10) which are greater than 6
→ pr(>6) = 4/10 = 2/5
There are 6 possibilities for the first dice, 6 for the second and 6 for the third. This makes 6x6x6 = 216 combinations. However, some of these combinations are duplicates if the order of the dice does not matter. For instance, we have counted both 5,2,3 and 2,3,5. To eradicate these duplicates, we must work out how many there are for each combination. If a combination ABC has been considered, then we have also counted ACB, BAC, BCA, CAB and CBA falsely. Thus every combination has been counted 6 times when we only needed to count it once. To get the correct value, we must divide 216 by 6, to get the true number of possible combinations as 36.
What are the odds of getting heads exactly twice when a coin is flipped 3 times?
Possibilities on the first toss = 2. For each of these . . .
Possibilities on the second toss = 2. Fo reach of these . . .
Possibilities on the third toss = 2.
Total possible sequances in 3 tosses = 2 x 2 x 2 = 8.
Number of ways to get heads exactly twice = 3 .
H - H - T
H - T - H
T - H - H
Probability of exactly 2 heads in 3 tosses = 3/8 = 37.5% .
Odds = 3 in 8, or 5 to 3 against it.
Why wont a sample statistics change from sample to sample?
The sample mean may differ from the population mean, especially for small samples.
How many hands of 13 cards containing all 4 aces can be dealt from a 52 cards?
The question is the same as:
"After removing the 4 aces from a standard deck, how many different hands
of 9 cards can be dealt from the remaining 48 ?"
The calculation is
48! / (39! x 9!) = (48 x 47 x 46 x 45 x 44 x 43 x 42 x 41 x 40) / (9 x 8 x 7 x 6 x 5 x 4 x 3 x 2)
We get 1,677,106,640 .

Rolling three dice what is the probablity of obtaining different outcomes?
Depends if the dice is bias then you an not have an answer if it is fair then you times 6 by 3 which = 18 so if you want three different outcomes then 3/18 which is simplified to 1/6 of a chance!
