Chanel rolls a 6-sided die {1,2,3,4,5,6), and then flips a coin {H,T}
Alexxx [7]

Answer:

5H

Step-by-step explanation:

Given

A roll of die followed by a flip of coin.

Required

Determine possible outcome in the sample space

Taking the experiment one at a time.

A roll of die will either give any of 1 to 6 as its outcome.

A flip of coin will either give any of H or T as its outcome.

So, the possible outcomes of a roll of die followed by a flip of coin is:

{1H,2H,3H,4H,5H,6H,1T,2T,3T,4T,5T,6T}

<em>Note that numbers came first because the question stated that the die is rolled first.</em>

<em></em>

Comparing the list of given options with the sample space above.

Option (A) i.e. 5H answers the question.

A wire, 224 cm long, is cut into 3 pieces. The first is twice as long as the second. The third is one-half as long as the second
vichka [17]
X = 1st piece, y = 2nd piece, z = 3rd piece

x + y + z = 224
x = 2y
z = 1/2y

2y + y + 1/2y = 224
3.5y = 224
y = 224/3.5
y = 64 cm<== 2nd piece

x = 2y
x = 2(64)
x = 128 cm...1st piece

z = 1/2y
z = 1/2(64)
z = 64/2
z = 32 cm....3rd piece
