The probability of getting first a red and then a black marble is 3/28.
What is probability?
The chance of happening an event out of all the possible outcomes is called the probability of an event.
The probability of red marble is P(Red) = Total red marbles/ Total marbles
P(Red) = 3/8
The probability of black marble is P(Black) = Total Black marbles/ Total marbles left considering no replacement of marble.
P(Black) = 2/7
The probability of getting first a red and then a black marble will be
P(Red and Black) = P(Red) x P(Black) = 3/8 x 2/7
P(Red and Black) = 3/28
Therefore, the probability of getting first a red and then a black marble is 3/28.
