Probability
The probability of a certain event is a number expressing the likelihood that a specific event will occur, expressed as the ratio of the number of actual occurrences to the number of possible occurrences. In mathematics, it is a measure of how often an event will happen and is the basis of statistics.

What is the probability of selecting a king or queen?
It depends on the context which is not specified. If picking a topic for a history project on the monarchy of some country it would be 1!
If it concerns selecting one card, at random, from a standard deck of playing cards, the answer is 8/52 = 2/13.
The increase in sample size will reduce the confidence interval.
The increase in standard deviation will increase the confidence interval.
The confidence interval is not based on a linear function so the overall effect will require some calculations based on the levels before and after these changes.
It would depend on the relative rates at which the change in sample size and change in standard deviation occurred. If the sample size increased more quickly than then standard deviation, in some sense, then the size of the confidence interval would decrease. Conversely, if the standard deviation increased more quickly than the sample size, in some sense, then the size of the confidence interval would increase.
What is the probability of drawing a red ten or a black ace?
The answer depends on
- whether the card(s) are drawn from a normal deck of playing cards,
- whether they are at random,
- how many cards are drawn,
- whether the cards are replaced before drawing the next card.
Thus, if 49 cards are drawn without replacement from an ordinary deck, whether randomly or not, the probability is 1.
For a single card drawn randomly, the probability is 1/13.

The probability of (1 or 2 or 3) on the first (or any) roll is 1/2 = 50% .
The probability of (4 or 5 or 6) on the second (or any) roll is 1/2 = 50% .
The probability of exactly that result on two rolls is (1/2 x 1/2)= (50% x 50%) = 1/4 = 25% .

What is the probability of winning a lotto?
The answer depends on the lotto. The relevant variables are:
- How many numbers you chose from,
- How many numbers you have to choose,
- How many numbers you need to match to win - something - not necessarily the jackpot.

How do you find probabilty of negative z score?
Let z be positive so that -z is the negative z score for which you want the probability.
Pr(Z < -z) = Pr(Z > z) = 1 - Pr(Z < z).
