WebIn probability and statistics, the expectation or expected value, is the weighted average value of a random variable. Expectation of continuous random variable E ( X ) is the expectation value of the continuous random variable X x is the value of the continuous random variable X P ( x) is the probability density function WebThe expected value of X may also be denoted as μX or simply μ if the context is clear. The expected value of a random variable has many interpretations. First, looking at the … WebIn general, the expected value of a random variable, written as E (X), is equal to the weighted average of the outcomes of the random variable, where the weights are based on the probabilities of those outcomes. We can talk about E (X), E (X 2 ), and so forth. If a is a constant, we can talk about E (X+a), E (X-a), E (aX), and so forth. batu pahat flood

"WebThe expected value of a difference is the difference of the expected values, and the expected value of a non-random constant is that constant. Note that E (X), i.e. the theoretical mean of X, is a non-random constant. Therefore, if E (X) = µ, we have E (X − µ) = E (X) − E (µ) = µ − µ = 0.

WebNote: $\cdot$ means multiply. So the probability that a head will appear $0$ times is $\frac{1}{8}$ if a student tosses a coin $3$ times. To see why the probability of there being $1$ head is $\frac{3}{8}$ see here.. Now as the expected value is the weighted average of all possible values, we need to sum the right hand column.
