Auniversity claims that 80% of its basketball players get degrees. an investigation examines the fate of all 20 players who entered the program over a period of several years that ended six years ago. of these players, 11 graduated and the remaining 9 are no longer in school. if the university's claim is true, the number of players among the 20 who graduated should have the binomial distribution with n = 20 and p = 0.8. use the binomial probability formula to answer the question, what is the probability that not all of the 20 graduate?

The probability of not all players graduate in approximately 0.988.

Step-by-step explanation:

Let's define,

= "Number of players that graduated"

We know that and the probability density function for a binomial random variable is:

, with

We want to know the probability that not all of the 20 graduate, in other words we want to know the probability of .

x + 4/7

step-by-step explanation:

use cymath

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
