Simpson's \( \frac{1}{3} \) rule is a numerical method for approximating definite integrals. For the rule to be applicable, the number of intervals must be even. This is because the formula involves pairing values from consecutive intervals, and for this pairing to be possible, the number of intervals must be divisible by 2.
Therefore, the correct condition is that the number of intervals is divisible by 2.
Let a random variable \( X \) follow Poisson distribution such that \( P(X = 0) = 2P(X = 1) \). Then, P(X = 3) = ______
The probability distribution of a random variable \( X \) is given as follows. Then, \( P(X = 50) - \frac{P(X \leq 30)}{P(X \geq 20)} \) =
