Answer:
0.1
Step-by-step explanation:
chance of pulling out a blue marble can be described as 8 equally probable outcomes (blue marbles) out of 20 equally probable outcomes (all marbles).
Similarly, the chance of pulling out a green marble is 5 out of 20.
In total, we have 8*5 (combinations of blue then green) outcomes out of 20*20 (any two marbles):
8*5 / (20*20) = 40 / 400 = 1/10 = 0.1
Where’s the cone? Is there a picture of a cone? I can’t really solve this, I’m sorry if I bother you
<span>18/37 if you're in Europe, 9/19 if you're in America, assuming the wheel isn't rigged.
If the roulette wheel is a fair wheel, the odds on any given spin of the wheel is unaffected by any previous spins of the wheel. So no matter how many times the wheel has consecutively come up red, the next spin can still come up red, black, or green based upon the number of each color is present on the wheel. The difference between the odds for Europe vs America has to do with a quirk about roulette. In Europe, the roulette wheel has 37 slots, 18 red, 18 black, and 1 green. In America, the roulette wheel has 38 slots, 18 red, 18 black, and 2 green.
Although in this case, I'd be wary about assuming that the wheel isn't rigged. The odds of 270 consecutive red on a fair wheel is only 1 in 3.09663x10^84 in Europe, or 1 in 4.14949x10^87 in America.</span>
Answer:
The average speed of Marshall is 29.7 mph
Step-by-step explanation:
Given;
distance traveled to work, d₁ = 27 miles
distance traveled back home, d₂ = 27 miles
initial time taken, t₁ = 1 hour and 20 minutes
final time taken, t₂ = 29 minutes
Total distance traveled, d = d₁ + d₂ = 27 miles + 27 miles = 54 miles
Total time taken for the journey, t = t₁ + t₂ = 1 hour + ( 20 mins + 29 mins)
t = 1 hour + 49 mins = 1 hour + 0.817 hour = 1.817 hour
The average speed is given by;
v = total distance / total time
v = 54 miles / 1.817 hour
v = 29.7 mph
Therefore, the average speed of Marshall is 29.7 mph
