Marie and her 4 friends went to the country to on her uncle robert's farm. marie said she saw 100 chickens and cows.her friend said she counted 252 legs.how many chicken and how many cows did they see

Step-by-step explanation:

I'd tell her that if (and only if) her prediction is correct, the probability of getting tails is 0.5.  Actually, the probability of getting heads would be the same, 0.5.

In real life she would not necessarily get 240 tails out of 480 tosses, but the mean value of the number of tails would indeed be close to 0.5.
