(a) The marble is red. (b) The marble is odd-numbered
Solving (a): Probability of Red.
This is calculated as:




Solving (b): Probability of Odd
Since each marble type is numbered 1 to 38, then half of it are odd.
i.e. 19 odd numbered red marbles and 19 odd numbered blue marbles.
So, the probability of odd is:

Answer:
The value of x is reduced to one third when the value of y is tripled.
Step-by-step explanation:
Here, y varies inversely with x.
⇒
Here, k = Constant of Proportionality.
⇒ k = x y .......... (1)
Now, given y' = 3 y
to find the value of x'
Putting the value in

or, k = 3 y x '.......... (2)
From above statement (1) and (2)
⇒ xy = 3yx'
or, x ' = x/3
Hence, the value of x is reduced to one - third when the value of y is tripled.
