Answer:
1/5, 2/5, 3/5, and 4/5
Step-by-step explanation:
The expected value per game is -0.26. Over 1000 games, you can expect to lose $263.16.
To find the expected value, we multiply the probability of winning by the amount of winnings, the probability of losing by the amount of loss, and adding those together.
We have a 1/38 chance of winning; 1/38(175) = $4.61. We also have a 37/38 chance of losing; 37/38(5) = $4.87.
$4.61-$4.87 = -$0.26 (rounded)
To five decimal places, our answer is -0.26136; multiplied by 1000 games, this is $261.36 lost.
Answer:
If a child took just one minute, distance is less than 0,8 km
Step-by-step explanation:
speed= 125 m/min = 0,125 km/min,
distance=0,8 km
time= 0,8 km / 0,125 km/min = 6,4 min.
The distributive properties of addition and subtraction can be used to rewrite expressions for a variety of purposes. In each case, you are distributing the outside multiplier to each number in the parentheses, so that multiplication occurs with each number before addition or subtraction occurs.
