Answer 2

number of successes/ number of trials

Question 3

probability of the complement of an event

Answer 3

P(A)=1-P(bar A)

Question 4

probability of independent events

Answer 4

P(A and B)=P(A) * P(B)

Question 5

probability of dependent events

Answer 5

P(A and B)= P(A) * P(BIA)

Question 6

probability of compound events

Answer 6

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

permutations

Answer 7

nPr= n!/(n-r)!
