Probability

There are no s's in a standard deck of cards, so the probability of selecting any s's, in any sequence of draws, in any strategy of replacement is exactly zero.

Coeff of Variation = Mean/SD

The probability is 10/50 = 1/5.

It depends on how many positions the spinner has, and on how many of them are a 5. The question, as stated, is incomplete and cannot be answered. Please restate the question.

if you flip a coin once, the chance it will be heads is 50%

Yes.

However, a z-score greater than 3 implies either that the outcome is rare (prob = 0.135%) or that some of the assumptions regarding the variable are incorrect. This could be the distribution itself or its parameters.

There are four 10's in a standard deck of 52 cards.

The probability of picking a diamond out of a standard deck of 52 cards is 13 in 52, or 1 in 4, or 0.25.

If you assume that the Ace is high, then the odds of drawing a card higher than a nine is a standard deck of 52 cards is 20 in 52, or 5 in 13, or about 0.3846.

If you assume that the Ace is low, then the odds of drawing a card higher than a nine is a standard deck of 52 cards is 16 in 52, or 4 in 13, or about 0.3077.

There is no possibility that a male will inherit and X-linked recessive allele from his father because for a male child the father only contributes the Y chromosome to his son (of the XY pair he has). If the fater's X chromosome has a recessive allele then it is 100% certain that he will pas this on to all his daughters.

The mean value of 100, 70, 70, and 20 is 65

Population distribution refers to the patterns that a population creates as they spread within an area. A sampling distribution is a representative, random sample of that population.

There are 7 letters, but three 'o's are indistinguishable, so there are 7! ÷ 3! ways = 840 ways.

If the 'T' and the 't' are also considered to be indistinguishable (that is ignoring the case of the letters; making "Toronto" and "toronTo", etc the same), then the number of ways is 7! ÷ (3! x 2!) ways = 420 ways.

! after a number means the factorial of the number which is the product of all numbers less than or equal to the number, and greater than or equal to 1. Thus:

7! = 7 x 6 x 5 x 4 x 3 x 2 x 1.

3! = 3 x 2 x 1

2! = 2 x 1

0! is defined to be 1.

HHHH, HHHT, HHTT, HTTT, TTTT.

Pr(HHTT) = 6/16 = 0.375

The probability of tossing a coin twice and getting tails both times is 1 in 4, or 25%.

If you have already tossed a coin and had it land on tails, the probability that it will land on tails again the next time you toss it is 50%.

In a standard deck, there are 13 spades and 4 kings and 1 king of spades.

the mishap probability component is an estimation that a hazard will result in a mishap

1 in 6. U would of thought it was 5/6 but there aren't five 5s on a dice. There's only1.

If p is the probability that an event will happen once, then the probability that it will happen just twice is p2. The probability it will happen 3 times is p3. The probability it will happen at least once ( ie once or twice or three times ore more times is p + p2 + p3 + ... = p(1-p). For "or" you add probabilities, for "and" you multiply probabilities.

Number of cards in a deck = 52

Number of cards that are spade = 13

Number of cards that are heart = 13

Probability that the card drawn is a spade and heart =

13/52 + 13/52

= 26/52 or 1/2

11 outcomes if the dice are indistinguishable, 36 otherwise.

Leaving aside leap years, the probability is 0.0137

If the faces on the 12 sided die are numbered from 1 to 12, then 1/12.
