The probability is p = 2/5, the correct option is the third one.
<h3>
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.

Answer:
Option B
Step-by-step explanation:
It's given that p + q has a value of
So the equation representing the relation will be,
p + q = --------(1)
Value of p is
p =
By substituting the value of p in the equation (1),
q =
q =
Therefore, Option B will be the correct option.
Answer: There are 944 lots the broker will realize from this subdivision.
Step-by-step explanation:
Since we have given that
For 10 acre tract,
Number of lots = 50 by 100 foot = 5000
If the tract has 85600 square feet, we need to find the number of lots.
Since 1 acre = 43560 square feet
so, 10 acres = square feet
Since there is direct variation, so it becomes,
Hence, there are 944 lots the broker will realize from this subdivision.
