|
Mutually exclusive events |
P(A or B) = P(A) + P(B) |
|
|
|
Not mutually exclusive events |
P(A or B) = P(A) + P(B) - P(A and B) |
|
|
|
Independent events |
P(A and B) = P(A) × P(B) |
|
|
|
Dependent/Conditional events |
P(A and B) = P(A) × P(B given A) |
|
|
|
SOH |
sin(x°) = opposite ÷ hypotenuse |

|
|
Area of a triangle |
1/2 × a × b × sinC |
|
|
|
Sine rule |
(sinA ÷ a) = (sinB ÷ b) = (sinC ÷ c) OR (a ÷ sinA) = (b ÷ sinB) = (c ÷ sinC) |
|
|
|
Cosine rule |
a² = b² + c² - 2 bc cosA |
