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.

If you were to flip a coin 4 times what is the probability of you getting at least two heads?
9/16
Answer:
There are 16 possible outcomes. The criteria (at least two heads) are met if the coins come up in any one of 11 different ways:
- One way with four heads: HHHH
- Four ways with three heads: HHHT, HHTH, HTHH, THHH
- Six ways with two heads: HHTT, HTHT, THHT, THTH, TTHH, HTTH
This would make the probability 11/16
What is the probability of tossing a 4 on a regular numerical cube?
The probability of tossing a 4 is 1 out of 6 sides, or 1/6. Hope this helps!
Why the value of a roll of two dice is normally distributed?
It is not! It is very approximately so and the key word there is approximately.
How does the science of probability affect decisions?
Probability is a subset of number theory. A huge branch of mathematics. It is not possible here to explain the ramifications of probability. Many of which are contrary to what appears to be common sense.
Probability is used by insurance companies for instance.
What is the probability that the number on the ball is greater than or equal to 26?
It depends on what the numbers on all the balls are.
When the population standard deviation is known the sampling distribution is known as what?
normal distribution
What is the shape of this sampling distribution?
No, your telepathic powers are not sending me the correct image to be able to answer the question!
What is the probability of making type 1 error when null hypothesis is true?
It is the same as the significance level of the test - often 5%.
What is the probability of the dealer busting in Blackjack?
Unfortunately, this all depends on what the deck is like (which cards have passed already), and what the up card is. There is no single answer which will work for an answer. However the greatest chance for the dealer to bust is when the dealer is showing a 4-5-6. The least chance is when they are showing a 9-10-A.
What is the probability of rolling a number cube 3 times and getting a number less than 3 each time?
Not Sure
How can you get a guy to notice you when he doesn't even know you exist?
just be friendly, smile and say hello as you walk past them, nothing more, it will get their attention and if you do this often enough they will most likely strike up a conversation with you.
Drop em' and go about your business, and if you really want him to notice you do something to catch his attention. (And I don't mean to bend over in front of him wearing a mini skirt trying to pick up a pencil.) Just try to carry on a conversation or something like start it off as a compliment and there you are.
What is the probability of rolling an even number on a standard 6 sided die?
A standard six-sided die has 3 even numbers and 3 odd ones, so the probability of rolling either an odd or even number would be 50-50.
What is the probability of rolling a number other than 3?
There are 6 sides of a die, and rolling a 3 is one of the 6 sides.
Therefore, there are 5 sides on the die which is not a 3.
So, (outcomes wanted)/(total outcomes) = 5/6
Event A: It is made up of only straight lines (T, E, N).
Event B: It is made up of only curved lines (S).
What is the probability of drawing a 3 out of a deck of cards?
There are four 3 cards in the deck of 52 cards. So the probability of drawing a 3
from the deck of cards is; P(3) =
4/52 =0.076923076... ~ 0.0769 ~ 7.69%.
Within 1 stdev of the mean - between 40 and 60.
Why are standard z values so important?
A z-score gives the distance (specifically number of standard deviations) from the mean so when you compare z-scores, it gives a direct comparison of how far from the mean the values are.
What is the probabilty of getting a heart from a ordinary pack of cards?
There are 52 cards in a deck with no jokers. There are 13 hearts in such a deck so the probability of drawing a heart is
13/52
