Probability
"one or more" = 1, 2 or 3 P(1) = 4/60 P(2) = 4/60 * (4-1)/(60-1) P(3) = 4/60 * 3/59 * 2/58 Either-or probabilities are found by adding the individual probabilities.

First, please do not use all capitals. Online it is like SHOUTING. Not only is it rude, but it is harder to understand. Thank you. Mean = ∑x/n 6 = (5+7+4+x)/4 Solve for x.

statistics
If the events are independent, the probability of both/all events occurring is determined by multiplying the probabilities of the individual events. a) .95^4 * .05^2 = ? B) "at least five" = 5 or 6 P(5) = .95^5 * .05 = ? P(6) = .95^6 Either-or probabilities are found...

The equation or formula for velocity is similar to speed. To figure out velocity, you divide the distance by the time it takes to travel that same distance, then you add your direction to it.
