Question

miki tosses a coin 50 times, the coin shows heads 28 times. Suppose the coin is fair and miki tosses it 500 times. how many times can she expect it to show heads?

Answer 1

280. all they did to 50 was add a 0 so add one to the 28 and you get 280 :)

Answer 2

The answer is 280 times, because 50 x 10 = 500, and the coin is fair, so you have to do 28 x 10, which equals 280.  So the answer is 280 times.  :D  Glad I could help!
