mutually exclusive events

P(A or B) = P(A) + P(B)

Independent events

P(A and B) = P(A) x P(B)

acceleration

a= (v-u)/t

velocity

vv = uu + 2as
v = u + at

displacement

s = (u+v/2)t
s = ut + 1/2att

P(A or B or both)

P(A) + P(B) - P(A and B)

You can model X with a binomial distribution, B(n,p) if:

- there are a fixed number of trials, n
- there are two possible outcomes (success and failure)
- there is a fixed probability of success, p
- the trials are independent of each other

What is a critical region?

A critical region is a region of the probability distribution which, if the test statistic falls within it, would cause you to reject the null hypothesis.

What is the actual significance level?

The actual significance level of a hypothesis test is the probability of incorrectly rejecting the null hypothesis.
