<h2>
Answer:</h2>
<em>(a). </em>
<em>(b). </em>
<h2>
Step-by-step explanation:</h2>
(a).
The number of Black marbles in the bag = 8
Number of White marbles in the bag = 5
Number of Yellow marbles in the bag = 3
Total marbles in the bag = 16
The probability is given by,
So,
Probability of drawing a<u> Black Marble first</u> is,
Now replacement is done.
So,
Probability of drawing <u>Yellow Marble second</u> is,
So,
<u>Probability is given by,</u>
<em><u>Therefore, the probability is,</u></em>
(b).
Number of Red marbles = 5
Number of Yellow marbles = 3
Number of White marbles = 8
Total marbles = 46
Probability of drawing a <u>Red marble first</u> is given by,
And,
Probability of drawing a <u>White marble second</u> is given by,
As, there is no replacement.
So,
Probability is given by,
<em><u>Therefore, the Probability is given by,</u></em>
