We have two experiments. For the first experiment, we will draw a card at random from a fair deck of cards (52 cards with 13 cards of each suit).For the second experiment we will draw a card at random from a different fair deck of cards.

Let event R1be defined as "the carddrawn from the first deck has a red suit", event B1be "the card drawn from the first deck has a black suit", event F2be "the card drawn from thesecond deck is a figure (Jack, Queen, King, or Ace)" and event N2be "the card drawn from the second deck has a number between 2 and 10".

What is the probability of the complement of event B1U N2?

a.1/13

b.2/13

c.4/13

d.1/4
