Answer:
1/12
Step-by-step explanation:
In a bag, there are 3 red marbles, 5 white marbles, and 2 blue marbles. One marble is selected and then it is not replaced. Find the probability of selecting a white marble 3 times in a row.
The total number of marbles in the bag is given as:
3 red + 5 white + 2 blue
= 10 marbles
The probability of selecting a white marble 3 times in a row without replacement is calculated as:
5/10 × 4/9 × 3/8
= 60/720
= 1/12
