Respuesta :

No, because the coin has 2 sides so it mostly likely wont let on heads them 20 times. Hope i helped u :)
Yes, it is possible, but very unlikely. There is two sides to a dice, so the probability of heads is 1/2 each time. (1/2)^20 would make the probability very low. So: Yes it is possible but no is is not likely.
