Probability

Ah, what a lovely question! It's actually "heads of state" when referring to the leaders of different countries. Remember, when we talk about multiple leaders, we keep "state" singular to show they are all part of the same concept. Keep painting with those words, my friend!

Oh, dude, the probability of guessing the last digit of a phone number is 1 in 10, because there are 10 possible digits (0-9). So, like, if you randomly guess, you have a 10% chance of getting it right. But hey, don't stress about it too much, it's just a phone number!

50%

Two coins tossed sample space is (H=Heads, T = Tails) as follows. HH, HT, TH, TT is the sample space.

Generally people who act and treat others well are treated well by others.
That is not to say that good things happen to them more than people who are less pleasant. Misfortune happens to the good, bad and the indifferent in equal measure. As does good fortune.

A matched test is appropriate only if the two variables are measures taken for the same subject.

6x6x6=216

Yes.

1/2

2 out of 12

This is going to be big. To simplify the idea some, start with the digit, and write Even & Odd. The even side will look exactly like the odd side. Then for the first letter, list all 26 letters. Then under each letter, list all 26 letters again. So under ODD you will have 676 letters. And the same under Even, for 1352. Looking at the odd side, you have the first tier P has 26 under it, and Q has 26 under it for 52. Then for the other 24 letters, each one has 2 'winners', so 48 more. So there are 100 winners out of 1352 total.

A lot of people have a difficult time getting over the red walls. This seems to mostly affect people on slower computers since timing is critical, and at slow frame rates it is hard to do the jump. The best way to get over these walls is to simply jump on top of one of the wooden blocks. Then jump again and start flying at the apex of the jump. You should now be able to just flyover the red wall.Many people have a hard time finding the marble. The passage to the marble is narrow, but there is a line of acorns marking the entrance. Just keep going to the end of the passage and the marble will be there.The correct way to do the marble bowling is to drop the marble and kick it into the batteries, however, you can also get a running start and just drop the marble. That will send it coasting into the batteries too, and this method is often more accurate than kicking.The slot car racing is really a no-brainer. Just hold down the throttle until the race is over - you'll win every time.

The answer depends on how many of the 5 cards are similar.

The probability of rolling a 4 is 3/36 .

The propbability of rolling 12 is 1/36 .

The probability of rolling either one is 4/36 = 1/9 = 111/9 percent.

We have to use the expression P(X=x) = nCx px (1--p)(n--x)

Here n = n and p=p and x = 1 or x>1

P(X>/=1) = 1 -- P(X</=1)

So, P(X<=1) = P(X=0) + P(X=1)

This gives nC0 p0 (1--p)(n-0)+ nC1 p1 (1--p)(n--1)

ie (1--p)n + n p (1--p)(n--1)

Bimodal Distribution

The probability of any one number on a die being rolled is 1/6 or 16.67%.

contaminate equipment

overwhelm med staff and resources

force personnel to use protective equip that degrades mission effectiveness

incapacitate and /or kill large number of personnel

You can't...unless it is not a traditional die

If you are counting each roll separately (if they are independentdent) then 1/6.

1/6

He has 10 green marbles.

It does not indicate anything if the mean is greater than the standard deviation.

It is 50/100 = 1/2
