find the expected value (μ) of the random variable with the given probability distribution.\nμ = ?\ndo not round your answer.
Answer
Explanation:
Step1: Recall expected - value formula
The formula for the expected value $\mu$ of a discrete random variable is $\mu=\sum_{i}x_{i}P(x_{i})$.
Step2: Calculate the product for each pair
For $x = 2$ and $P(2)=0.03$, the product is $2\times0.03 = 0.06$. For $x = 3$ and $P(3)=0.09$, the product is $3\times0.09 = 0.27$. For $x = 4$ and $P(4)=0.18$, the product is $4\times0.18 = 0.72$. For $x = 5$ and $P(5)=0.31$, the product is $5\times0.31 = 1.55$. For $x = 6$ and $P(6)=0.33$, the product is $6\times0.33 = 1.98$. For $x = 7$ and $P(7)=0.06$, the product is $7\times0.06 = 0.42$.
Step3: Sum up the products
$\mu=0.06 + 0.27+0.72 + 1.55+1.98+0.42$ $=5.0$
Answer:
$5.0$
