Divide the number of times she picked a color by the total times she picked a pen:
Red = 6/30 reduces to 1/5
Blue = 10/30 reduces to 1/3
Black = 14/30 reduces to 7/15
The probability of picking a blue pen , then a red pen is found by multiplying the two possibilities together:
1/3 x 1/5 = 1/15
There is a 1/15 probability.
Answer:
B. 650 Roast Beef, 490 Tuna, 900 Turkey
Step-by-step explanation:
As this chart displays the order that occured in one week, in order to find the estimate for the month is to multiply the values on the chart by how many weeks there are in a month.
As there are 4 weeks in a months, we can multiply each value by this ratio
Roast Beef: 
Tuna: 
Turkey: 
As this is an estimate, we are looking for the option that is the closest to these estimated values.
Option B is the closest to these values.
Im pretty sure
a = 65
b= 80
Answer:
Where?
Step-by-step explanation:
There are the combinations that result in a total less than 7 and at least one die showing a 3:
[3, 3] [3,2] [2,1] [1,3] [2,3]
The probability of each of these is 1/6 * 1/6 = 1/36
There is a little ambiguity here about whether or not we should count [3,3] as the problem says "and one die shows a 3." Does this mean that only one die shows a 3 or at least one die shows a 3? Assuming the latter, the total probability is the sum of the individual probabilities:
1/36 + 1/36 + 1/36 + 1/36 + 1/36 = 5/36
Therefore, the required probability is: 5/36
