Answer #1

wne n (6G) 36 2 36 1+22 4 13,2+2, 3+ 26since there is maximum 3 rolls possible not more than that so p(x>3) is impossible event that means probability will be zero. So the correct option is (d) none of these

    Shandelle rolls a pair of fair dice and sums the number of spots that appear on the up faces. She then flips a fair coin the number times associated with the sum of the spots. For example, if she rolled a 3 and a 4, then she flips the fair coin 7 times. If the coin flipping part of the random experiment yielded an equal number of heads and tails, find the probability that she rolled an 8 on the...
