Twenty percent of adults in a particular community have at least a​ bachelor's degree. Suppose x is a binomial random variable t

hat counts the number of adults with at least a​ bachelor's degree in a random sample of 100 adults from the community. If you are using a calculator with the binompdf and binomcdf​ commands, which of the following is the most efficient way to calculate the probability that more than 60 adults have a​ bachelor's degree, ​P(xgreater than​60)?

Answer:

P(X>60) = 1-binomcdf(100,0.20,60)P (X \leq 60)

Step-by-step explanation:

As we have to find an efficient way for the probability as follows:

P(X>60)

First of all we will find the remaining part of the probability that is:

P (X\leq 60 )

As the given probability is inclusive of 60 so the formula used will be:

P(X\leq 60)=binomcdf(100,0.20,60)

Now going back to the actual probability, the formula used will be:

P(X>60) = 1-binomcdf(100,0.20,60)

(Because the total probability is always 1)

I hope it will help you!

I don't understand the substitution method?
liq [111]
It depends on what variable you are tying to solve for first. Say you are trying to solve for x first and then y on the first problem you wrote.

In substitution you solve one of the equations for example with
6x+2y=-10
2x+2y=-10
you solve 2x+2y=-10 for x

2x+2y=-10
-2y = -2y (what you do to one side of the = you do to the other)
2x=-10-2y (to get the variable by its self you divide the # and the variable)
/2=/2 (-10/2=-5 and -2y/2= -y or -1y, they are the same either way)
x=-5-y

now you put that in your original equation that you didn't solve for:
6(-5-y)+2y=-10 solve for that
-30-6y+2y=-10 combine like terms
-30-4y=-10 get the y alone and to do this you first get the -30 away from it
+30=+30
-4y=20 divide the -4 from each side
/-4=/-4 (20/-4=-5)
y=-5

now the equation you previously solved for x can be solved for y.
x=-5-y
x=-5-(-5) a minus parenthesis negative -(- gives you a positive
-5+5=0
x=0

and now we have solved the problem. x=0 and y=-5

Can someone help me? It's urgent and thank you!
Alex_Xolod [135]

Answer:

15.2%

Step-by-step explanation:

There are 12 marbles in total and there are 5 red marbles, so the probability of getting a red marble is 5/12. There are now 11 marbles and there are 4 blue marbles. So the probability of getting a blue marble is 4/11.

You multiply these 2 values together.

5/12 * 4/11 = 20/132 = 0.1515

This is about 15.2%
