Using probability distribution liste
x. 0. 1. 2. 3
P(x). 0.2. 0.1. 0.3. 0.4
A- find the mean ,variance,and standard deviation
B- what is the probability that p(x is at least 1)?
C-what is the probability that p(x is less than 3)?
Population size:4Mean (μ): 1.5
Variance (σ2): 1.25
Standard deviation (σ): 1.1180339887499
B. the probability that p(x is atleast 1) is 3/4
C. the probability that p(x is less than 3) is 3/4
Please Best :)
