It is known that 50% of adult workers have a high school diploma. If a random sample of 6 adult workers is selected, what is the probability that 3 or more of them have a high school diploma? (That is, find P(X f$displaystyle geq f$ 3) (round to 4 decimal places)

0.6563

Step-by-step explanation:

Given: The probability that adult workers have a high school diploma : p= 0.50

Sample size : n= 6

Let x be the number of workers have high school diploma.

Binomial distribution formula,

Now, the probability that 3 or more of them have a high school diploma will be:

Hence, required probability = 0.6563

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
