A penny, nickel, and dime are simultaneously flipped. What is the probability that heads are showing on at least 6 cents worth o
Nastasia [14]

Answer:

5/8

Step-by-step explanation:

The number of possible outcomes after flipping 3 coins is $2 \times 2 \times 2 = 8$. If the dime isn't heads, we need both the penny and nickel to be heads. If the dime is heads, the other two could be anything. So there are a total of $1+(2 \times 2)=5$ ways for us to get at least 6 cents. The answer is $\boxed{\dfrac58}.$

Luis walked one-eighth of the distance to school. What part of distance to school does he still need to walk?
klio [65]
<span>Total Distance = x
Luis walked one-eighth of x = x(1/8) = x/8 
He still need to walk = Total Distance - Distance covered
He still need to walk = x-x/8
He still need to walk = (8x-x)/8

He still need to walk = 7x/8
He still need to walk = x(7/8) 
He still need to walk seven-eighth of the total distance.
