Answer:
3/8
Step-by-step explanation:
Given:
Box has 5 red + 4 white =9 balls
Two marbles are drawn without replacement.
To find:
The probability that the first marble is also white.
The second ball drawn is white hence white ball left =3.
Total ball left =8
Hence the probability that the first marble is also white is 3/8
