Each of three identical jewelry boxes has two drawers. in each drawer of the first box there is a gold watch. in each drawer of the second box there is a silver watch. in one drawer of the third box there is a gold watch while in the other there is a silver watch. if we select a box at random, open one of the drawers and find it to contain a silver watch, what is the probability that the other drawer has the gold watch?

Let's call the two drawers of the first box, both containing gold.

Let's call the two drawers of the second box, one containing silver, and one containing gold.

Let's call the two drawers of the third box, both containing silver.

If you opened a drawer containing silver, you opened either or .

If you opened , the other drawer is , and thus contains gold.

If you opened , the other drawer is , and thus contains silver.

If you opened , the other drawer is , and thus contains silver.

So, in one case out of three, the other drawer containes gold, and the probability is

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles

hi there!

the answer will be d: 2
