The probability is p = 2/5, the correct option is the third one.

How to find the probability?</h3>
There is a total of 6 socks, such that 4 are black and 2 are blue.
Then the probability of first getting a black sock is the quotient between the number of black socks and the number of blue socks, which gives:
P = 4/6
Now there are 5 socks in total, such that 3 are black and 2 blue.
Then the probability of getting another black one is:
Q = 3/5
The joint probability (getting the two black socks) is given by the product of the individual probabilities:
p = (4/6)*(3/5) = 2/5
The correct option is the third one.

If you divide a fraction over a number, you can just muplitply the denominator (the number under the line) by the number by which you divide:
99 and 21 are divisible by 3, so we can divide them both by it:
but that's all we can do!
so let's multiply
and it's its simplest form
Answer:
7/13=b
Step-by-step explanation:
-11b+7=2b
7=13b add 11 b to both sides
b=7/13 divide by 13
