You rolled a number cube 50 times. your results are shown in the table below. number frequency 1 4 2 9 3 6 4 12 5 9 6 10 what is the experimental probability of rolling a 3? 3/25 12/25 3/50 12/50

6/50 = 3/25 --> Answer A

Option 1 -

Step-by-step explanation:

Given : You rolled a number cube 50 times. Your results are shown in the table below.

Number     1          2         3         4         5        6

Frequency  4         9          6         12        9       10

To find : What is the experimental probability of rolling a 3?

Solution :

Total number of outcomes = 50

Frequency of rolling a 3 = 6

The experimental probability of rolling a 3

Therefore, Option 1 is correct.

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
