report a problem

1/12

Step-by-step explanation:

2 red marbles + 3 green marbles + 4 blue marbles = 9 marbles

First drawing:

You want a green marble out of 3 green marbles out of the total of 9 marbles.

p(green marble) = 3/9 = 1/3

Second drawing:

After drawing the green marble, there are 8 marbles left. There are 2 red marbles.

p(red marble) = 2/8 = 1/4

p(green then red) = 1/3 * 1/4 = 1/12

step-by-step explanation:

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
