Wayne flips a weighted magic trick coin 100 times. If the coin landed on heads just 19 times out of 100 , how many times is the coin expected to land on tails out of 800 flips? (Hint: the probability that the coin will land on heads is not equal to 0.5 .) A 152 B 648 C 800 D 912

152 (Answer A)

Step-by-step explanation:

The experimental probability of obtaining a head is 19/100, or 0.19.

If the coin is flipped 800 times, the expected number of heads will thus be:

0.19(800 flips) = 152  (Answer A)
