The second option - 3/25.
The probability of the first one is 3 blue socks over 10 socks in total = 3/10
The probability of the second one is 4 red socks over 10 socks in total = 4/10
Multiply the two probabilities to get the probability of having the first sock as blue and the second sock as red.
3/10 * 4/10 = 3/25

Answer:
4x2−25
Step-by-step explanation:
(2x+5)(2x−5)
=(2x+5)(2x+−5)
=(2x)(2x)+(2x)(−5)+(5)(2x)+(5)(−5)
=4x2−10x+10x−25
4x2−25
