There are a total of 4 queens in a standard deck of 52
cards. The probability that the 2 consecutive draws are queen is:
Probability = (4 / 52) * (3 / 51)
<span>Probability = 12 / 2652 = 0.004</span>
Answer:
The standard deviation of the data set is
.
Step-by-step explanation:
The Standard Deviation is a measure of how spread out numbers are. Its symbol is σ (the greek letter sigma)
To find the standard deviation of the following data set

we use the following formula

Step 1: Find the mean
.
The mean of a data set is the sum of the terms divided by the total number of terms. Using math notation we have:


Step 2: Create the below table.
Step 3: Find the sum of numbers in the last column to get.

Step 4: Calculate σ using the above formula.
