Answer:
1/5
Step-by-step explanation:
The question says that 3 blacks coins are in a bag as well as 3 red coins.
A coin is picked at random without replacement and another coin is picked again.What is the probability of both coins picked been a black.
P(B)= 3/6 which is also 1/2
Probability of second coin picked been black again will be
P(B) = 2/5( if one coins is picked and not replaced the total number of coins left will reduce)
Therefore,the probability of this happening will be
1/2×2/5= 1/5
