DOLE found that 83% of Filipinos think that having a college education is important to succeed in life. If a random sample of 7 Filipinos is selected, find the probability that at most two people will agree with that statement.

The experiment consists of counting the number of events that will occur during a specific interval of time or in a specific distance, area, or volume.

Five balls numbered 1, 2, 3, 4, and 5 are placed in a box. One is selected, its number is noted and then it is replaced. If this experiment is repeated many times, find the variance of the numbers on the balls.

These are the most important characteristics of any probability distribution.

It is applied when the probability of success are not the same from trial to trial.

The normal curve is asymptotic.

It is a perfectly symmetric, mound-shaped distribution.

Five hundred raffle tickets are sold at ₱25 each for three prizes of ₱4,000, ₱2,500, and ₱1,000. After each prize drawing, the winner ticket is then returned to the collection of tickets. What is the mean or expected value if a person purchases four tickets?

The most common way to measure the spread of a normal distribution.

It is commonly referred to as a normal curve, or bell curve.
