Answer:
A.) With replacement = 1/27
B.) Without replacement = 2/91
Explanation:
Given the following :
Red marbles = 10
Blue marbles = 5
Probability that all 3 marbles are blue;
A.) With replacement :
Total no marbles = 10 + 5 = 15
P(First pick equals blue) = 5/15 = 1/3
P( second pick equals blue) = 5/15 = 1/3
P( third pick equals blue) = 5/15 = 1/3
P(blue blue blue) = (1/3) × (1/3) × (1/3) = 1/9
B.) Without replacement :
P(First pick equals blue) = 5/15 = 1/3
P( second pick equals blue) = 4/14
P( third pick equals blue) = 3/13
P(blue blue blue) = (1/3) × (4/14) × (3/13 )
= 12/546 = 2/91
