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.

The probability of rolling an even die and then an odd die is (3 in 6) times (3 in 6), which is the same as (1 in 2) times (1 in 2), which is the same as 0.5 time 0.5, which is 0.25.
Twins are not necessarily identical. They can be fraternal as well. Identical twins result when one fertilized egg splits in two. Fraternal twins result from two fertilized eggs.
What is the ratio of 4 blue marbles to 6 white marbles?
The ratio of 4 blue marbles to 6 white marbles can be said as 4:6, 4 to 6, or 4/6.
This can then be simplified to 2:3 by a factor of 2.
What is the probability of rolling an odd number on a 20 sided dice?
Assuming the sides are labelled one to twenty and that all sides are the same shsp and size and that the dice in not biased in any way, then there will be a 50% chance of getting an odd number.
(4/52)*(3/51)*(2/50) = 24/132600 = 0.000181
What is a run of five cards of different suits?
A run of 5 cards, all sequential ( Ace, 2, 3, 4, 5, different suits) for example, in poker is known as a straight.
If these sequential runs of cards are of the same suit, then they are known as a straight flush.
It is 13.2%
"Dice" is both singular and plural. Usually, it's one "die" and two "dice."
What is the probability of 1 6 4 on 3 rolls of a die?
What is the probability of 1, 6, 4, on 3 rolls of a die
Why is an increase in the number of varieties of a good regarded as a gain from trade?
More varieties provide buyers with more options. More options allow buyers to better match their needs and costs, thus achieve more value for their money.
When tossing 5 coins simultaneously what is the probability that at least 1 head is showing?
Probability of no heads = (0.5)^5 = 0.03125
Probability of at least one head = 1 - probability of no heads = 1 - 0.03125 = 0.96875
Two six sided dice are rolled which number has the lowest probability of being rolled?
If two six sided fair dice are rolled, the sum of the result of both dice that has the
lowest probability to come up is 2 and 12. P(2) = 1/36. P(12) = 1/36.
How many ways can 5 friend sit together at the movies in 5 seats?
120 ways if ABCDE is considered different from EDCBA. In these two cases, the same people are next to one another , only the left and right re changed.
The probability of getting a red chip on the first draw is 5/15.
The probability of getting a red chip on the second draw, given that the first draw
gave a red chip that was not replaced in the bag is 4/14.
The probability that the first and second draw give a red chip is ;
5/15 x 4/14 = 2/21 ≈ 0.0952 = 9.52 %
If there were just 7 green and 4 blue involved you would need to pick out at least 8, since this would cover picking out all the greens plus 1 blue. Any choice of less than 8 might produce only greens.
Now in the case where we have 7 green, 4 blue and 5 red marbles we would need to choose 7 + 5 + 1 = 13, since any number less than 13 could be covered by selecting (by chance) all the 7 greens and all the 5 reds with no blue at all.
In this case the answer is found by totalling all numbers other than the smallest, and then adding 1.
Probably "high tension lead" (UK English) which translates to "high voltage wire" in American English which as far as automotive use goes usually refers to a "secondary ignition wire" also commonly known as a "spark plug wire".
"high tension lead" or "high voltage wire" could also refer to a high voltage wire (usually orange in color) used in a gas/electric hybrid vehicle. These wires carry much lower voltages than ignition wires, but at much higher current so they're much better suited for being involved in an accidental death of a service worker.
What color of streak is marble?
Marble, being composed almost entirely of the mineral calcite, would have a white streak. The same colour as calcite's streak.
The sample space consists of all the possible outcomes. A flip of a coin has 2 outcomes, H,T. The total number of outcomes for 6 flips are 26 or 64.
