The six faces of a fair cube are numbered 1 through 6. If the cube is rolled 300 times, what is the expected number of times a 5 will land face-up?

Answer:

m=1

Step-by-step explanation:

x1,y1 (2,2)   x2,y2 (8,8)

m=8-2/8-2

m=1

Answer:

2

Step-by-step explanation:

It sounds like we are pretending A is the universe.  The only numbers in our world are 1,2,3,4, and 5.

You are given B is all numbers greater than 2.

The complement of B would all the elements not listed in B.

The elements in B are 3,4, and 5, since we are looking for numbers greater than 2 in our world of numbers above.

The elements not in B are 1 and 2.

So B complement is {1,2}.

There are 2 elements in our set for B complement. The elements that were counted were just the element 1 and the element 2.

There are 2 items in the complement of set B.  The correct answer is:2

The complement of set B, denoted as B', contains all the elements that are NOT in set B.

Set B consists of all numbers greater than 2.

Therefore, the elements in B' will be all the numbers that are NOT greater than 2, which means all numbers less than or equal to 2.

Set B' = {1, 2}

So, there are 2 items in the complement of set B.

The correct answer is:2
