\250 doctors from three countries in Europe meeting in a conference to decide whether to approve a new vaccine for the flu. Among these are 115 Germans, 65 French, and 70 Englishmen. We also know that, 75% of the Germans, 60% of the French and 65% of the Englishmen are in favor of using the new vaccine. (a) What is the probability that a randomly chosen doctor is in favor of the vaccine

0.683 = 68.3% probability that a randomly chosen doctor is in favor of the vaccine

Step-by-step explanation:

(a) What is the probability that a randomly chosen doctor is in favor of the vaccine

75% of 115/250 = 0.46(German).

60% of 65/250 = 0.26(French).

65% of 70/250 = 0.28(Englishmen). So

0.683 = 68.3% probability that a randomly chosen doctor is in favor of the vaccine

y > 1/3x

y < = -x + 4
