A sock drawer contains 5 different colors of socks. It has 20 white, 10 black, 10 gray, 6 red, and 4 purple. If you reach into the drawer and choose a sock randomly, what is the probability you will get a black sock?
I just got it right on my assignment, and the correct answer is 1/5
It's 1/5. I just got it on the assignment that I just took on Edgenuity.
To find the probability of choosing a black sock, we need to determine the total number of socks in the drawer first. Then, we can calculate the number of black socks in relation to the total number of socks.
In this case, the total number of socks can be found by summing up the quantities of each color:
Total socks = 20 white + 10 black + 10 gray + 6 red + 4 purple = 50 socks
Next, we can find the number of black socks in the drawer. According to the given information, there are 10 black socks.
So, the probability of choosing a black sock can be calculated by dividing the number of black socks by the total number of socks:
Probability of choosing a black sock = Number of black socks / Total socks
Probability of choosing a black sock = 10 / 50
Simplifying this fraction, we get:
Probability of choosing a black sock = 1/5
Therefore, the probability of randomly selecting a black sock from the sock drawer is 1/5 or 0.2, which is 20%.
I looks like you have a total of 50 socks
10 of them are black
prob(drawing 1 black sock) = ....
