Answer:
The probability of selecting a marble that is not red, replacing it and then one that is white is 0.2102
Step-by-step explanation:
Number of red marbles = 7
Number of blue marbles = 12
Number of yellow marbles = 6
Number of white marbles = 9
Total marbles = 7+12+6+9=34
Probability of selecting red marble =
Probability of selecting no red marble =
Now replacing it one marble is drawn again
So, Probability of getting white marble
So,the probability of selecting a marble that is not red, replacing it and then one that is white =
Hence the probability of selecting a marble that is not red, replacing it and then one that is white is 0.2102
