Question

The help divide a group into 4 teams, the teacher brought out a bag with equal numbers of 4 different sticks (green, yellow, blue, and red).With 28 students randomly picking a stick, what is the probability that the first stick drawn will be green?

Answer 1

There are 7 green sticks.

There are 28 sticks in total.

p(green sticks) = (number of green sticks)/(total number of sticks)

p(green stick) = 7/28 = 1/4 = 0.25

Answer: 1/4 or 0.25

Answer 2

If there are 28 students, we can assume that there are also 28 sticks. There are 4 different colors, with the same number of sticks of each color. So, to find how many sticks of each color there are, we can do 28/4 = 7 sticks.

The probability of the first stick being green would be 7 (since there are 7 green sticks possible to choose from) / 28 (since there are 28 sticks total). This simplifies to:

7/28 = 1/4
