Aand b are independent events. p(a)=0.40 and p(b)=0.30. what is p(a and b)?

C. 0.12

Step-by-step explanation:

Independent events

The outcome of one event does not affect the outcome of the other. If A and B are independent events then the probability of both ocurring is:

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

With P(A) = 0.40 and P(B) = 0.30 then

P(A and B) = 0.40 x 0.30 = 0.12

can you rephrase the question ? it is unclear : -)

step-by-step explanation:

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
