Webb16 okt. 2024 · The estimate of P (X>12) should be as close as possible to the true value of P (X>12). And you can do that estimation by estimating maximizing the likelihood, but the likelihood is not equal to this P (X>12). The value P (X>12) is the parameter to be optimized. – Sextus Empiricus Oct 16, 2024 at 20:10 Show 1 more comment 1 Answer … Webb23 sep. 2014 · 1 Answer Sorted by: 1 If you want at least 1, you could just calculate the probability of having none and take the difference to 1: 1-dbinom (0,12,.2) I guess you could think about it, since it is hinted in the second part of the problem.

Webb14 dec. 2024 · One probability rule that's very useful in genetics is the product rule, which states that the probability of two (or more) independent events occurring together can be calculated by multiplying the individual probabilities of the events. For example, if you roll a six-sided die once, you have a 1/6 chance of getting a six. WebbProbability distributions are theoretical distributions based on assumptions about a source population. The distributions assign probability to the event that a random variable has a specific, discrete value, or falls within a specified range of continuous values.

Webb2 mars 2024 · If a random variable X follows a uniform distribution, then the probability that X takes on a value between x1 and x2 can be found by the following formula: P (x1 &lt; X &lt; x2) = (x2 – x1) / (b – a) where: x1: the lower value of interest x2: the upper value of interest a: the minimum possible value b: the maximum possible value WebbProbability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
