Given that a person is in the 36-and-over age group, what is the probability that the person applied to more than one school (to 4 decimals)? What is the probability that a person is 24-26 years old or applied to more than one school (to 4 decimals)? Suppose a person is known to have applied to only one school. What is the probability that the person is 31 or more years old (to 4 decimals)? Is the number of schools applied to independent of age?SelectYes, because the conditional probabilities all equal the marginal probabilitiesNo, because the conditional probabilities all do not equal the marginal probabilitiesItem 5
