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
