Answer:

Yes she made an error. Explanation is below.

Step-by-step explanation:

Let the sample space for a six sided number cube be S

$n(S) = \{1,2,3,4,5,6\}\\n(S) = 6$

Let the event of a number getting greater than two be B

$n(B) = \{3,4,5,6\}\\n(B) = 4$

To find:

the probability of complement of B that is

p(~B) = ?

Solution"

First we need to solve probability for number getting greater than two

$p(B) = \frac{n(B)}{n(S)}$

Now substituting the values we get

$p(B) = \frac{4}{6}$

$p(B) = \frac{2}{3}$

but we need complement of B so

$p(\textrm{complement of B)} = 1 - p(B)\\p(\~B) = 1 - p(B)\\p(\~B) = 1 - \frac{2}{3}\\ =\frac{1}{3} \\$

P(complement of rolling a number greater than two) = $\frac{1}{3}$

What are the solutions on the following system?

Oksana_A [137]

2x+y = -5. Solve this for y. We get y = -2x - 5. Find y^2: 4x^2 + 20x + 25. Substitute 4x^2 + 20x + 25 for y^2 in the first equation:

x^2 + 4x^2 + 20x + 25 = 25

Then 5x^2 + 20x = 0, so that x = 0. Subst. 0 for x in the 2nd eqn and find the value of y. Write your solutions as shown above: ( , ) and ( , ).

Your class is holding elections to choose a leadership committee of 4 students. If there are 30 students in the class, how many

AURORKA [14]

we have given that 30 students .

we need to choose committee of 4 students .

so the formula used here $nCr_{}$ .

where n is the total number of students.

and r is the student chosen from total.

so the possibility of choosing a commitee of 4 from 30 is

$nCr=30C4=\frac{30*29*28*27}{1*2*3*4} =27405$ .

so there 27405 possibilities can exist.

260 x .3= 78

260-78=182

than for the weights i did

120 x .3= 36
