Question 3The current enrollment (as reported by the university database) in this courseconsists of14 women3 menAssuming the probability of men enrolling is equal to the probability of womenenrolling, what was the percent probability that we would get exactly thisdistribution? (Use the binomial expansion to calculate the answer.)Question 4The previous question assumed a 50:50 ratio, but the actual ratio of women:menenrolled in liberal arts colleges in the US in 2021 was 60:40. Using this as the basisfor your probability calculation, what was the percent probability that we would getexactly a 14:3 distribution?

As per bartelby guideline expert have to answer first question only..

One headline was false, and the other was true, but the students did not know this. The probability that a student selected at random believed the true headline was 89% and the probability that the student believed the false headline was 85%. She found that 7896 of the students believed both headlines. a. In this sample, are the events "believed the false headline" and "believed the true headline" mutually exclusive? Explain b. Find the probability that a randomly selected student from this sample believed the true headline OR believed the false headline.
