Probability

There are 4 eight cards, and 12 face cards including the Jack, Queen and King.

So 4 +12 =16, which is the number of eight and face cards you have in a standard deck.

To find the probability, we will have 16/52 = 0.308

ummm, probability?

The risk of an accident - fatal or otherwise - is not constant over a person's lifetime. Young and inexperienced drivers or elderly drivers with slower reflexes, for example, are at higher risk. Also, different age groups make different numbers of road trips. In real life, therefore, it is quite unreasonable to extrapolate the 1 fatal accident in 4 million trips to 50,000 trips.

The answer is False

this is for 5-card poker

(4*2^5) which gives you 128, that's your m

devide it by n, which is the possibilities of hand draws (8C5)

so it will be 128/1712304

and that's your answer.00007547

There are four 5 and four 9 cards. Thus 8 out of 52 cards are 5 or 9.

In all there are 12 ! ways. If Mr and Mrs S are treated as a single unit, then there are 11! ways of arranging the 10 other people with Mr and Mrs S together.

But these can be Mr-Mrs or Mrs-Mr so, in fact, there are 2*11! ways in which Mr and Mrs S are together.

So the number of ways in which they are NOT together is 12! - 2*11!

= 399,168,000

This may not make sense, but it takes a concept known as z-scores into account, which basically standardizes everything.

if repeating is allowed than 1/263= 1/17576, if repeating isn't allowed than it's 1/(26*25*24)=1/15600.

The probability that, when rolling three dice none will come up odd is broken down by the probability that on odd roll will occur as an independent event. Rolling the first die has a probability of 3/6 that it will be odd. Rolling the second has the probability of 3/6 that it will be odd. Rolling the third has a probability of 3/6 will be odd. Rolling three and coming up with odd is really the probability that no odd numbers occurred, so therefore an even number DID happen (3/6), and an even number DID happen (3/6), and an even number DID happen (3/6). That's really just 1 - (3/6^3) or simplified 1 - (1/2^3). So therefore the probability that an odd number occurred in 3 die rolls is about 87.5%.

you are finding the probable answer in a question

EXAMPLE: Michelle has 10 cards. She is giving 2 to Shannon. What would the fraction, the dot (decimal) and the percent be?

ANSWER: The fraction is... 2-10

The decimal is... .20

The percent is...20%

Theoretical probability is the number of ways something can occur divided by the total number of outcomes. So, the theoretical probability of throwing a coin and it landing on heads is 1/2 or 0.5 or 50%.

3/4

The only way a tail doesn't show up is if all heads come up.

P(all heads) = (1/2)*(1/2)=1/4

P(at least one tail)=1-P(all heads)=1-(1/4)=3/4

Consider a coin toss. The probability of the coin coming up head is 1/2, the probability of the coin coming up tails is 1/2. No matter how many times you flip the coin the probability of any particular toss coming up heads or tails is always 1/2.

BUT

If you consider two coins tosses as a set then you have four possible outcomes:

first coin heads - second coin heads, first coin heads - second coin tails,
first coin tails - second coin heads, first coin tails - second coin tails

for ease of demonstration lets denote heads as H and tails as T

the above combination would then be HH,HT,TH,TT

the probability of any one of the combinations would be 1/2 for the first coin and 1/2 for the second coin so all combinations have a probability of 1/4. (1/2x1/2=1/4 I hope you realize.)

But, if we don't care which coin is H or T then the two combinations HT and TH are the same and we combined their probabilities into one 1/4+1/4=1/2

HH,(HT,TH),TT

1/4 1/2 1/4

Answer: 1/6

It does not matter what number the first die lands on: you will always have a 1/6 chance that the second die makes a total of 7: if it lands on a 6 while the first was 1; if it lands on a 5 while the first was 2; and so on.

Since there are 6 possible outcomes, and you want the probability of obtaining one of the outcomes (in your case 6), the probability of it landing on a 6 is 1/6.

Random lottery numbers, every time! I think it's great to mix it up, but I also like to see my numbers before I buy my ticket. I play the euro millions a bit more than the lottery as the rollover jackpots always look appealing! In theory it doesn't matter how you select the numbers so long as you pick the rquired number of numbers.
