The table shows the results of rolling a number cube, with sides labeled 1 through 6, several times. What is the experimental probability of rolling a 1 or a 5?

Express your answer in simplest form.

Outcome 1 2 3 4 5 6
Number of times outcome occurred 10 6 4 8 6 6

Answers

Answer 1
Answer:
Total number of rolls in the experiment:  (10 + 6 + 4 + 8 + 6 + 6)  = 40 .

Number of times  '1'  or  '5'  came up:  (10 + 6) = 16 .

Experimental probability of  '1'  or  '5'  :   16/40  =  40%
(Could change, and most likely will, in the next experiment.) 

Theoretical probability:  2/6  =  33-1/3 %

A rectangle has sides of length 6 yards and 5 yards. What is the perimeter?

Answers

Solutions 

We know that a rectangle has four sides and the perimeter of a rectangle is the distance around the outside of the rectangle.The opposite sides of a rectangle are congruent To find the perimeter you have to use the formula 2 × (Side A + Side B). 

We have the side lengths 6 yards and 5 yards. 

Solve 

2 × (Side A + Side B) 
2 × ( Side A (6) + Side B (5) )  
= (6 x 2) + (5 x 2) 
= 22 

The perimeter is 22 yards².  
P = 2l + 2w
Am I right with the formula?
The P= 2(6)+2(5)
P=12+10
P=22 yards
