Let P(E) represent the probability of event E. Let A and B be events with P(A) = 0.3 , P(B) = 0.7, and P(A and B) = 0.2 . What is the value of P(A or B) ?

Alina fully simplifies this polynomial and then writes it in standard form. xy2 – 2x2y + 3y3 – 6x2y + 4xy2 if alina wrote the last term as 3y3, which must be the first term of her polynomial in standard form? xy2 5xy2 –8x2y –2x2y
