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

Answer for problem 8 is D) Jessica

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.
