We have 3 white balls in the first urn out of 9. That means we have a 1 in 3 chance at picking the white ball in the first urn.

Now, we have a 3 in 11 chance at picking the white ball in the second urn.

Since, we want them simultaneously, we need to multiply them.

1/3 × 3/11 = 1/11 chance

SashulF [63]

Answer:

The number of machines to complete job in 2 hours is 6.

Step-by-step explanation:

Using the relation of the rate of each one machine and knowing that adding up both rates.

  1. Rate R +Rate S= Rate total

Rate R = \frac{x}{36}  'x' is the job

Rate S = \frac{x}{18}  'x' is the job

So, using the equation of rates

        Rate total =\frac{x}{36} + \frac{x}{18}

Rate total is going to be a job in 2 hours so = \frac{1}{2}

\frac{1}{2} = \frac{x}{36}+\frac{x}{18} <em>adding up</em>

\frac{1}{2}= x*\frac{3}{36}  <em>factoring the x</em>

\frac{1}{2}= x*\frac{1}{12}  <em>simplifying</em>

x= \frac{12}{2} \\

x= 6
