Answer 1

Answer #1

Solution

Given that ,

p = 0.42

1 - p = 0.58

n = 20

x = 7

Using binomial probability formula ,

P(X = x) = ((n! / x! (n - x)!) * px * (1 - p)n - x

P(X = 7) = ((20! / 7! (20 - 7)!) * 0.427 * (0.58)20 - 7

= 0.1502

Probability = 0.1502

High school seniors with strong academic records apply to the nation's most selective colleges in greater numbers each year. Because the number of slots remains relatively stable, some colleges reject more early applicants. Suppose that for a recent admissions class, an Ivy League college received 2,851 applications for early admission. Of this group, it admitted 1,030 students early, rejected 857 outright, and deferred 964 to the regular admission pool for further consideration. In the past, this school has admitted 18%...
