Why is only one normal table need to find any probability under the normal curve?
A normal distribution is defined by its mean and standard deviation, which are sufficient to describe the entire curve. Once you know these two parameters, you can use the standard normal table (Z-table) to find probabilities for any normal distribution by standardizing values. This process involves converting any normal variable to a standard score (Z-score), which allows you to utilize the same table for all normal distributions. Therefore, only one normal table is needed for any probability under the normal curve.
What value of Z from the standard normal distribution table has an area to the left probability equal to 0.0764?
-1.43 (approx)
What is the probability of rolling a dice 7?
With a single throw of a normal die, the probability is 0.With a single throw of a normal die, the probability is 0.With a single throw of a normal die, the probability is 0.With a single throw of a normal die, the probability is 0.
Is normal distribution a discrete probability?
No. Normal distribution is a continuous probability.
In what branch of mathematics would one use a normal distribution table?
A distribution table would be primarily used in the field of statistics and probability. Collecting and interpreting data is much easier when compiled in this format.

What is the probability of drawing a seven of hearts?
The probability on a single random draw, from a normal deck of cards, is 1/52.The probability on a single random draw, from a normal deck of cards, is 1/52.The probability on a single random draw, from a normal deck of cards, is 1/52.The probability on a single random draw, from a normal deck of cards, is 1/52.
Is normal distribution also a probability distribution?
Yes. When we refer to the normal distribution, we are referring to a probability distribution. When we specify the equation of a continuous distribution, such as the normal distribution, we refer to the equation as a probability density function.
What is the probability of having a normal child?
The probability is zero! There is no such thing as "normal". Every child (and adult) has some unique characteristics and that makes them not normal - in that respect.
How do you construct data table and the probability density?

What requirements are necessary for a normal probability distribution to be a standard normal probability?
For a normal probability distribution to be considered a standard normal probability distribution, it must have a mean of 0 and a standard deviation of 1. This standardization allows for the use of z-scores, which represent the number of standard deviations a data point is from the mean. Any normal distribution can be transformed into a standard normal distribution through the process of standardization.
What is the probability that a kickoff will go between 60 and 75 yards if the average kickoff is 50 yards with a variance of 49?
Change the data to a standard normal distribution and use the table to calculate the probability (areas). * For 75 yd: Z=(75-50)/7 = 3.57; from table area = 0.9998 (use 3.49 value). * For 60yd: Z=(60-50)/7 = 1.43; from table area = 0.9236. Subtract the two areas and you have the probability; 0.9998-0.9236 = .0762 or 7.62%.
