Scientific notation is used to write really large numbers, or really small numbers using less digits. For example:
1. Earth's distance from the sun 150,000,000 kilometers. We can rewrite this in scientific notation as 1.5 x
2. The length of a skin cell is 0.00003 meters. We can rewrite this in scientific notation as 3.0 x
3. The world population is about 7,000,000,000. We can rewrite this in scientific notation as 7 x

The probability that, for any day, the number of special orders sent out will be exactly 3 is 0.1633.
<h3>What are some of the properties of Poisson distribution?</h3>The Poisson distribution is a discrete probability distribution that describes the likelihood of a specific number of events occurring in a specified span of time or space, if these events occur at a constant mean rate and regardless of the time since the last occurrence.
Let X ~ Pois(λ)
Then we have:
E(X) = λ = Var(X)
Since standard deviation is the square root (positive) of variance,
Thus,
The standard deviation of X =
Its probability function is given by
Given the mean is 4.2.
We have to find the probability that on any day, the number of special orders sent out will be exactly 3. Therefore, the value of x will be 5.
Using the Poisson distribution,
Hence, the probability that, for any day, the number of special orders sent out will be exactly 3 is 0.1633.
