Since she has the most heads come up, making her chances to be best of getting heads.

Divide each of the four values (102, 164, 75, 139) by 250 to get
102/250 = 0.408
164/250 = 0.656
75/250 = 0.300
139/250 = 0.556
We see that Jessica's empirical probability of 0.556 is closest to that of 1/2 = 0.500 which is the theoretical probability of getting heads.
La réponse au problème 7
est B) Kelly
La réponse au problème 8
est D) Jessica
102/250 = 0,408
164/250 = 0,656
75/250 = 0,300
139/250 = 0,556
Nous voyons que la probabilité empirique de Jessica de 0,556 est la plus proche de celle de 1/2 = 0,500 qui est la probabilité théorique d'obtenir des têtes.
