The number of homes sold by a realtor during a month has the following probability distribution:
| Number Sold | Probability |
| 0 | 0.10 |
| 1 | 0.40 |
| 2 | 0.50 |
The standard deviation of the number of homes sold by the realtor during a month is the closest to _______.
A) 0.44
B) 1.40
C) 0.66
D) 1.35
The standard deviation of the discrete random variable X is calculated as SD(X)=σ=σ2−−√.SD(X)=σ=σ2.
The variance of the discrete random variable X is calculated as Var(X) = σ2=∑(xi–μ)2P(X=xi).
