PROBABILITY EXERCISE
For the following probability practice questions, use the following formulas. NOTE: the
account for
formulas are in the basic format and may require slight modification to account for
subsequent events. Identify the correct formula, set-up the equation correctly, then
calculate the correct final answer (round to two decimals). Each formula is used twice.
D(A) = Number of events classifiable as A
Total number of possible events
Formula 1:
Formula 2:
p(A or B) = P(A) + P(B) - P(A and B)
Formula 3:
p(A or B) = P(A) + P(B)
Formula 4
p(A and B) = P(A) Xp(BIA) = P(A) X p(B)
Formula 5:
p(A and B) = P(A) x p(BIA)
