a number cube is rolled 120 times. the number 4 comes up 47 times. what is the experimental probability of rolling a 4
A) 47/120 ; 1/30
B) 47/120 ; 1/6
C) 4/47 ; 1/6
D) 1/6 ; 47/120
There must be more to the question, as in each choice, two answera are given.
experimental: 47/120
And theoretical??
To find the experimental probability of rolling a 4, you need to divide the number of times the 4 came up by the total number of rolls.
In this case, the number 4 came up 47 times out of 120 rolls.
Therefore, the experimental probability of rolling a 4 is 47/120.
So, the correct answer is A) 47/120 ; 1/30.
To find the experimental probability of rolling a 4, we need to divide the number of times the number 4 came up by the total number of rolls.
In this case, the number 4 comes up 47 times out of 120 rolls. So, the experimental probability of rolling a 4 would be 47/120.
Therefore, the correct answer is option A) 47/120 ; 1/30.
