Probability
A random variable X has a _____ distribution where it can take any values that are infinite, and hence uncountable.
What is continuous probability distribution?
Customer satisfaction survey results (measured on a 1-5 scale). Is it discrete or continuous?
Discrete
Number of road accidents in a month in Cagayan de Oro City. Is it discrete or continuous?
Discrete
Refer to the probability that a random variable is less than or equal to a specified value.
What is Cumulative Probability?
A measure of how far a set of data are dispersed out from their mean or average value
What is Variance?
The discrete probability distribution that gives only two possible results in an experiment, either Success or Failure.
What is Binomial Distribution?
From past experience, a company has found that in carton of transistors, 92% contain no defective transistors, 3% contain one defective transistor, 3% contain two defective transistors, and 2% contain three defective transistors. Calculate the mean
