Answer:
0.02 or 2%
Step-by-step explanation:
Theoretical probability calculated by dividing the number of events you want to calculate(green marble) with the total event possible(red + blue + green). There are 4 red marbles, 5 blue marbles, and 1 green marble. The probability will be: 1/(4+5+1)= 1/10= 10%
The result of the experiment is:
Red=22
Blue= 24
Green=4
Experimental probability calculated by dividing the number of events occurs with the total number of trials. We pull green 4 times and do 50x pulls, so the probability is: 4/50= 8%
Difference between the theoretical probability and the experimental probability is: 10%- 8%= 2%
4+1, 3+2, 2+3, 1+4. 4 total combinations, unless 4+1 and 1+4 are the same. In that case, there are only 2, 1+4, and 2+3
Answer:
480.02
Step-by-step explanation:
The answer is 480.02 because its asking what is the diffrence meaning subtraction being 480.02
Answer:
The variance is 3.2
Step-by-step explanation:
step 1
Find the mean
[78+79+79+81+83]/5-------> 400/5------> 80
step 2
for each number: subtract the Mean and square the result
(78-80)²----->4
(79-80)²----> 1
(79-80)²----> 1
(81-80)²----> 1
(83-80)²----> 9
step 3
work out the mean of those squared differences
[4+1+1+1+9]/5-----> 16/5-----> 3.2----> this value is called the "Variance"
