What is the probability of rolling a die and getting a 3 the first time?
There are 6 sides on a die, so the denominator should be 6. The number 3 appears on the dice once, so the fraction probability should be 1/6.
What is the probability of obtaining exactly four tails in five flips?
Assume the coin is fair, so there are equal amount of probabilities for the choices.There are two possible choices for a flip of a fair coin - either a head or a tail. The probability of getting a head is ½. Similarly, the probability of getting a tail is ½.Use Binomial to work out this problem. You should get:(5 choose 4)(½)4(½).(5 choose 4) indicates the total number of ways to obtain 4 tails in 5 flips.(½)4 indicates the probability of obtaining 4 tails.(½) indicates the probability of obtaining the remaining number of head.Therefore, the probability is 5/32.
What is the difference between experimental and theoretical probability?
The difference between experimental probability and theoretical probability is that experimental probability is the probability determined in practice. Theoretical probability is the probability that should happen. For example, the theoretical probability of getting any single number on a number cube is one sixth. But maybe you roll it twice and get a four both times. That would be an example of experimental probability.
Should the numbers for the experimental probability be close to the theoretical probability?
Not necessarily. There may not even be a way to work out a theoretical probability. Furthermore, there is always a chance, however small, that the experimental probability is way off.
What are the characteristics a standard normal probability distribution?
I apologize my question should have read what are the characteristics of a standard normal probability distribution? Thank you
How many times should kareen expect to win if he spins the arrow 10 times?
To determine how many times Kareen should expect to win when spinning the arrow 10 times, we need to know the probability of winning on a single spin. If, for example, the probability of winning is 0.3 (or 30%), then he can expect to win about 3 times in 10 spins (10 spins × 0.3 probability = 3 wins). Adjust the expected number of wins based on the actual probability of winning in the game.
Experimental probability of rolling the sum of 2?
That means that you should roll a die many times, count how often you get the number "2", then divide this by the total number of rolls. If the die is "fair" (no extra weight on one side), you would expect this experimental probability to be somewhere close to the theoretical probability of 1/6, at least, if you roll often enough.
Why should probability always include a number?
Probability is a numerical value and there must bea number, not just include one.
If I roll a dice 100 times how many times should I expect to see the number three?
When rolling a fair six-sided die, the probability of rolling a three on any single roll is 1/6. If you roll the die 100 times, you can expect to see the number three about ( \frac{1}{6} \times 100 ), which is approximately 16.67 times. Therefore, you should expect to see the number three about 17 times in 100 rolls.
What are the most common winning 3 numbers?
All numbers should have the same probability of appearing. The fact that some number appeared (by chance) more often in the past, has no bearing on the future probability.All numbers should have the same probability of appearing.

A typical expectation in actual practice is that estimates should have a probability of being met of the time?
A typical statement in the field is the desire to "have a 95 percent probability of meeting time and cost estimates."
What is a numerical probability?
Probability is a numerical measure. Occasionally, though, it is expressed in words such as very likely or not at all likely. But these phrases are (or should be) based on the fact that probability itself is a number.
A radom number generator is used to select a number from 1 to 100 What is the probability of selecting the number 153?
The probability should be 0 (zero). 153 is not between 1 and 100. If you meant your number generator to return a number between 1 and 1000, the probability would be 1/1000 = .001 = .1%
What is the probability of drawing a red number card from a deck of cards?
13 out of 52. _____________________ It should be 20 out of 52 if Ace is included as a number card. Not including ace the probability is 18 out of 52.
What would the theoretical probability be of flipping a coin four times?
Anyone can flip a coin four times so I say 100 percent probability. On the other maybe you should ask the odds of the results from four flips.
When purchasing a new home how much good faith down payment should you expect on 350000.00 home?
Ten percent
If you roll a die 30 times how many times should you expect to roll a number less than 3?
The expected number of rolls under 3 is the number of rolls times the probability of rolling less than 3. So: E(rolls less than 3 out of 30) = 30 * 1/3 = 30/3 = 10
