Answer:
Probability that first sock is blue is 0.33 and Probability that second sock is red is 0.16
Step-by-step explanation:
Number of red socks = 2
Number of white socks = 6
Number of blue socks = 4
Total socks in drawer = 2+6+4 = 12
The formula used to calculate probability is:
We are given you draw out a sock, return it, and draw out a second sock.
We need to find the probability that the first sock is blue and the second sock is red?
Using formula:
Probability that first sock is blue = 4/12 = 1/3 = 0.33
Probability that second sock is red = 2/12 = 1/6 = 0.16
So, Probability that first sock is blue is 0.33 and Probability that second sock is red is 0.16
Answer : B
the distance between the points (4,3) and (2,-1)
We apply distance formula
(x1,y1) is (4,3)
(x2,y2) is (2,1)
d^2 = 4+16 = 20
Take square root on both sides
So
the distance between the points (4,3) and (2,-1) is 2sqrt(5)
