Calculating probability, statistics assignment help

If a box has 7 red flowers and 5 white flowers, what is probability that we will pick a red flower if a flower is picked at random from the box? Let us say that we put the flower in our first pick back into the box. What will then be the probability that we will pick a red flower in our second pick if a flower is picked at random from the box? Now let us assume that the flower in our first pick is set aside and not put back in the box. What will then be the probability that we will pick a red flower in our second pick if a flower is picked at random from the box?
