Standardising the observation ensures that the mean is 0 and the standard error is 1. Otherwise the plot could be located anywhere and be concentrated or spread out.
What is the probability of getting a sum of 5 if the dice is tossed 120 times?
Prob(at least one 5 in 120 throws) = 1 - prob(no 5s in 120 throws)= 1 - (5/6)120= 0.999 999 999 69 = almost 1.
Prob(at least one 5 in 120 throws) = 1 - prob(no 5s in 120 throws)= 1 - (5/6)120= 0.999 999 999 69 = almost 1.

Why are there fifty-two cards in a pack?
If your question refers to the structure of the cards, there are four suits, each with 13 cards:
A,2,3,4,5,6,7,8,9,10,J,Q,K
If your question refers to why these cards were selected, the popular answer is that there are four suits for the four seasons and thirteen cards in each because there are thirteen weeks in a season. As you can see, the 52 cards correspond with the fact that a year has 52 weeks.
What is the probality of picking 23 of hearts in a deck of cards?
The probability of picking a 23 of hearts in a standard 52 card deck of cards is zero, because there is no 23 of hearts.
If you meant to ask about the probability of picking a 2 or a 3 of hearts, then the probability is 2 in 52, or 1 in 26, or about 0.03846.
A playing card is dropped 3 times What is the probability of it landing face up all three times?
1/2 * 1/2 * 1/2 or 1/8
No, a probability must needs be a number between 0 and 1.20% might be a probability, though - since that is equivalent to 0.2.
