Answer:

Probability = 0.12

Step-by-step explanation:

Given : A drawer contain  4 red, 3 white , 3 blue socks

Total number of outcomes(S)= 10

Favorable event for first sock(B) ={3 blue sock}=3

Probability of picking first sock which is blue = favorable outcome/ total number of outcome P(B) = 3/10

since replacement is there

therefore, total no of outcomes remain same = 10

Favorable event for second sock(R) ={4 red sock}=4

then, probability of picking second sock which is red =favorable outcome/ total number of outcome P(R) = 4/10

Now, probability that the first sock is blue and the second sock is red is

P(B and R)= P(B) × P(R) = 3/10 ×4/10 = 12/100 = 3/25

Probability of events = 0.12

Solve by square rooting : 3(X+2)^2:8​
dolphi86 [110]

The value of x is √8/3 - 2

Step by step explanation:

The given equation is

3(x+2)^2=8

To find x,

(x+2)²= 8/3

By taking square root on both sides

x+2= √8/3

x=√8/3 -2

x= -0.37

Thus the square root for the given value is -0.37
