Answer:
5/156
Step-by-step explanation:
First, how many pieces?
1 red+ 5 green + 7 yellow = 13 pieces
We draw a piece
The probability it is green
P(green) = number of green/ total
= 5/13
Now there are only 12 pieces left
Probability the second piece drawn is red
P(red with 1 piece removed) = number of red/ total left
= 1/12
P(green, then red) = P(green) * P(red with 1 piece removed)
= 5/13 *1/12
=5/156
Add 1, then add 2, then add 3, then 4, then 5, then 6.
Answer: 0.6666... (never ending digit)
Step-by-step explanation:
2/3 divide the numerator, '2' by the denominator '3'
Answer:
13.3
Step-by-step explanation:
There is an equation that helps
mean= (All of the numbers in the data added) divided by (the number of numbers in the data)
What that mean is:
1.) Add 20, 5, 7, 17, 16, and 15
2.) divided by 6 (because there is 6 numbers in the data)
3.) round it to the nearest number (numbers from the one's place being 4-0 means go back or 5-9 means go forward a number)
which in this case it should be 13.33333...=13.3
