Suppоse thаt yоu hаve 11 cаrds. 5 are red and 6 are black. The cards are well shuffled. Yоu randomly draw two cards with replacement. • R1 = first card drawn is red • R2 = second card drawn is red Hint Video on Independent Events Textbook Pages P(R1 AND R2) = [response1] Round your answer to two decimal places. P(At least one red) = [response2] Round your answer to two decimal places. P(R2|R1) = [response3] Round your answer to two decimal places. Are R1 and R2 independent? [response4]
