There is a bag filled with 3 blue and 4 red marbles. A marble is taken at random from the bag, the colour is noted and then it is replaced.
Another marble is taken at random.
What is the probability of getting exactly 1 blue?

5/7 is the answer to your question

81 seats

49/100 represents the experimental probability of the coin landing heads up.
