Every continuous random variable X has a probability density function P DF written f x that satisfies the following conditions. What is the probability that the battery life for an iPad Mini will be at least 11 hours. For it to function as a probability density it is necessary that it integrates to one.
2 If she leaves the house on the market for another month what is the mathematical expression for the probability density function of the sales price.
While it is not obvious that the normalization factor is the correct value for this to be true it is the one fact that I state here without proof. What is the probability that the battery life for an iPad Mini will be 10 hours or less. This function is positive or non-negative at any point of the graph and the integral of PDF over the entire space is always equal to one. The probability density function PDF of a random variable X allows you to calculate the probability of an event as follows.
