Two conditions under which we can assume that the sample means follow a normal distribution are as follows:
1). If the sample size is large enough, n greater than or equals 30, the sampling distribution is approximately normal regardless of the shape of the population.
2). In order to be considered a normal distribution, a data set (when graphed) must follow a bell-shaped symmetrical curve centered around the mean.

Answer:
We use tree diagram by connecting relevant samples
Step-by-step explanation:
thats all
We know, Circumference = 2π * x/2 = <span>π x
In short, Your Answer would be: Option B
Hope this helps!</span>
THE ANSWER WOULD BE X=2/3
N 2-1 < 3
n is equal to :
2-1 = 1 so n would have to be 1 in order to be less than 3
