Final answer:
To find the probabilities of drawing specific marbles from a bag where each marble is removed after being drawn, we need to consider the number of each type of marble and the total number of marbles in the bag. Then, we divide the number of desired marbles by the total number of marbles to get the probability.
Step-by-step explanation:
The bag still contains four blue and three white marbles. Maria draws one marble from the bag at random, records the color, and sets the marble aside. The probability of drawing blue on the first draw is 4. Suppose Maria draws a blue marble and...
