Answer:
dependent, 39/155
Step-by-step explanation:
Since the checkers are not replaced, the events are dependent since the number of checkers in the bag when you pick the second time depends on the first pick.
31 checkers—13 red and 18 black.
P(red) = red/ total
= 13/31
Keep the checker
Then 30 checkers—12 red and 18 black.
P(black) = black/ total
= 18/30 = 3/5
P ( red, keep,black) = 13/31 *3/5
39/155
Answer:
<u>Option D is answer.</u>
Step-by-step explanation:
Hi there!
From the question;
Speed (s) = 600 miles/hr
Distance (d) = 3000 miles
Time (t) = ?
We know that;
Speed (s) = ![\frac{Distance(d)}{Time (t)}](https://tex.z-dn.net/?f=%5Cfrac%7BDistance%28d%29%7D%7BTime%20%28t%29%7D)
600 = ![\frac{3000}{t}](https://tex.z-dn.net/?f=%5Cfrac%7B3000%7D%7Bt%7D)
t = ![\frac{3000}{600}](https://tex.z-dn.net/?f=%5Cfrac%7B3000%7D%7B600%7D)
Therefore, it will take 5 hours to fly 3000 miles.
Hope its helps!
