Which set of events is an example of dependent events?
A dependent event is one that relies on something else to happen. For instance with a mouse trap the trap closing "depends" on the trigger being activated.
What is the term for a variable that causes something else to change in an experiment?
an independent variable
How can stock price react randomly to events that have more than 50 percent probability of happening?
Stockbrokers and traders are human beings. They may read an event differently, have different predictions on it's consequences, or react to it differently based on emotions, media attention, or something else entirely.
What is the probability of something ever happening?
Something just happened. As something would have to happen to make nothing happen, the probability of something else happening is approximately 100%.If you have a more specific definition of something, probability can be calculated by [# of events] divided by [# of possible outcomes].For example:> The chances of rolling a 1 or a 2 on a 6-sided diecalculated by 2[either rolling a 1 or rolling a 2] divided by 6[either rolling a 1 and rolling a 2 and rolling a 3 and rolling a 4 and rolling a 5 and rolling a 6]2/6 = 1/3 = One in Three ~ 33.333%> The chances of something happening (the Time variable is irrelevant) calculated by ∞[infinite number of somethings] divided by ∞[infinite possible occurences of something]∞/∞ = 1 = 100%
What is 3 out of 8?
Your 3 out of 8 is a fraction representing 3/8ths. It could be odds in some kind of exercise in probability. The activity yields a 3 in 8 chance of a given outcome. As an expression of odds, it's 3 to 8 (or 3:8). Same 3 in 8 chances of a given outcome. In probability, the range is from 0 (no chance whatever of the event happening) to 1 (it is going to happen and no force in the universe will preven it). To convert 3 out of 8 in to probability, we divide 3 by 8 and get 0.375 for the probability. We can convert that to something else, and we get 375 out of 1000 for a "new" representation.
