Answer 2

Calculating the Probability of Selecting a Green Tea Bag

To calculate the probability of randomly selecting a green tea bag from the box, we can use the following formula:

Probability (P) = (Number of green tea bags) / (Total number of tea bags)

Given that there are 17 green tea bags and 3 black tea bags in the box, the total number of tea bags is 17 + 3 = 20.

Applying the Formula

Using the formula, the probability of selecting a green tea bag can be calculated as:

P = 17 / 20

Calculating the Probability

Therefore, the probability of randomly selecting a green tea bag from the box is:

P = 17 / 20

So, the probability of selecting a green tea bag is 17/20.
