Less. The more times the coin is tossed, the more likely it will reflect the actual odds of .5 heads and .5 tails.


Two coins are going to be tossed 780 times Predict the number of times 2 heads will be tossed?

Half the time they will be the same, half the time they will be different. Half of the time that they're the same they will be heads, half the time they are the same they will be tails. It's your homework, YOU figure it out. The way I figure it. There are four options: 1) heads / heads 2) heads / tails 3) tails / heads 4) tails / tails By process of chance, one out of four times both coins will be heads/heads. Therefore 780/4 = 195 times.
