<h2>Therefore x=2 and y= 1</h2>

Step-by-step explanation:

Given equations are

y = 6x -11                    and         -2x -3y = -7.........(2)

⇒y - 6x = -11.......(1)

Equation (2)× 3 - Equation (1)

-6x -9y -(y-6x) = -21 -(-11)

⇔-6x -9y-y+6x=-21+11

⇔-10y = -10

⇔y=1

Putting the value of y in equation (1) we get

1 = 6x -11

⇔x =2

Therefore x=2 and y= 1

Suppose you have a 6-face unfair dice with numbers 1,2,3,4,5,6 on each of its faces. If the probability distribution of throwing
kotegsom [21]

Answer:

D is correct

Step-by-step explanation:

Here, we want to select which of the options is correct.

The correct option is the option D

Since the die is unfair, we expect that the probability of each of the numbers turning up

will not be equal.

However, we should also expect that if we add the chances of all the numbers occurring together, then the total probability should be equal to 1. But this does not work in this case;

In this case, adding all the probabilities together, we have;

1/12 + 1/12 + 1/12 + 1/12 + 1/12 + 1/2

= 5(1/12) + 1/2 = 5/12 + 1/2 = 11/12

11/12 is not equal to 1 and thus the probability distribution cannot be correct
