There are 7 marbles, including 3 green ones, so at the start, there is a 3/7 chance of getting a green marble.
Assuming you did get a green one, there are now 6 marbles left, with 2 blue marbles, so there is a 2/6 chance of taking a blue marble.
Given that both have to happen, you must multiply each probability, hence the total probability is 3/7 x 2/6, or a 1/7 chance.
Hope this helped

Answer: 50 miles per hour
Step-by-step explanation:
The average speed of the car will be gotten by using the formula:
= Distance/Time
where,
Distance = 65 miles
Time = 14:48 - 13:30 = 1:18 hours = 1 hour 18 minutes = 1 18/60 = 1.3 hours
Speed = Distance / Time
= 65 miles / 1.3 hours
= 50 miles per hour
