Probability

It depends on how many times you throw it!

On a single throw, the answer is 0.5

At the Olympics, the probability is 1

At a kindergarten, the probability is 0!

three

You cannot. If you are told the standard deviation of a variable there is no way to tell whether that was derived from grouped or ungrouped data.

With all other factors being equal, ie Queen of Diamonds vs Queen of Spades, no. no suit trumps another in hold em.

Although the probability of this event is greater than zero, it is so very small that for all intents and purposes it is taken to be zero.

It is 8/52 or 2/13

The answer depends on how many marbles are picked and on whether or not they are returned to the jar before picking the next one. Since you have not bothered to provide any information on either of these aspects, I cannot provide a more useful answer.

120 times 5factorial

sample size is the specific size of a thing like the how long or wide.

while sample unit is the whole thing not referring to specific number size.

if your talking about Julius ceaser he was crazy

The answer depends on the numbers on the cards in the bag!

The answer is 7C5 = 21.

37 cards.

The goal is to disregard the influence of sample size. When calculating Cohen's d, we use the standard deviation in teh denominator, not the standard error.

It really depends on where you live. Probably about an 83.75 percent chance right now.

With standard dice, zero.

There are 52 outcomes.

Ways to roll 4:

1 + 3

2 + 2

3 + 1

Three ways out of 36 possible combinations = 3/36 = 1/12

Your total possible number of combinations: 62 = 36

Combinations that can add up to 7:

1-6

2-5

3-4

4-3

5-2

6-1

So your odds of rolling a seven would be 6/36, or 1/6.
