    (Problem a) The events are dependent because you're looking for a specific product. (Problem b) Now, assuming that the cubes have six faces: P(blue is less than 3)= 2/6 = 1/3 The product is 8; 1*8=8, but there is no 8 on a die. So blue must be 2 and yellow

    The events are independent, so event A would be multiplied by event B. (Event A =rolling an even #) (Event B =rolling a 6). The probability of event A = 1/2 The probability of event B = 1/6 To solve: P(even then 6)= 1/2*1/6 = 1/12 = 0.083 Therefore, there
