Red Cards = 10
Other Cards (Black + Blue) = 10+20 = 30
So, the ratio would be: 10/30 = 1/3
So, your final answer is 1/3
Hope this helps!
Answer:
3 / 500
Step-by-step explanation:
so .006 is in the thousandths so you first put it like 6/1000 but you can't forget to simplify. So the answer is 3 / 500

Answer:
The standard deviation for the number of people with the genetic mutation in such groups of 1000 is 9.49.
Step-by-step explanation:
Standard deviation: It is a measure of how spread out numbers are. It is the square root of the Variance, and the Variance is the average of the squared differences from the Mean.
The given parameters are:
Proportion, p = 10%
Sample size, n = 1000
The standard deviation is calculated as:
σ=
So, we have:
σ=*(1-10%)
Evaluate:
σ= 9.49
Hence, the standard deviation for the number of people with the genetic mutation in such groups of 1000 is 9.49.
