Answer:
(a)The probability that both marbles are blue=5/18
The probability that both marbles are yellow=1/6
(b)The probability that exactly one marble is blue=5/9
Step-by-step explanation:
Blue marbles=5
Yellow marbles=4
Total marbles=5+4=9
(a)
Probability of drawing first blue marble=5/9
Probability of drawing second blue marble without replacement=4/8
The probability that both marbles are blue
Probability of drawing first yellow marble=4/9
Probability of drawing second yellow marble without replacement=3/8
The probability that both marbles are yellow
(b)
The probability that exactly one marble is blue
=Probability of first blue marble (Probability of second yellow marble)+Probability of first yellow marble (Probability of second blue marble)
The probability that exactly one marble is blue
=
=
=

Step-by-step explanation:
We take ~p∧~q∨r to mean (~p∧~q)∨r because "and" normally has precedence over "or." The (~p∧~q) term will only come into play when both p and q are false. It will only affect the outcome if r is also false. This condition is the last line of the table.
To find how many times greater you have to divide.In this question the bases are the same. This means you can use the exponent law for division.
The exponent for division sates that if you are dividing numbers with the same base but different exponents you can subtract the exponents.
(8.76 x 10e6)divided by (<span>8.76 x 10e2)
The answer of that is 8.76x10e4
This is because e6-e2 is e4
Therefore 8.76x10e6 is 10e4 times greater than 8.76x10e2</span>
