The probability that he selected the special quarter is 87.5%.

<h3><u /></h3><h3><u>Probability</u></h3>

Given that Mandvil has one standard quarter and one special quarter with a Head on both sides, and he selects one of these two coins at random, and without looking at it first, he flips the coin three times, to determine, if he flips a Head three straight times, what is the probability that he selected the special quarter, the following calculation must be made:

  • 1 - (standard quarter) = X
  • 1 - (0.50^3) = X
  • 1 - 0.125 = X
  • 0.875 = X
  • 0.875 x 100 = 87.5

Therefore, the probability that he selected the special quarter is 87.5%.

I need help its math
Degger [83]

Given: w²+9=6w [0, 3, 6, 9]

We need to substitute each number for w and find which works

Sub Zero: 0²+9=6×0

Simplify: 9=0. 9 does not equal 0, so it is not 0

Sub Three: 3²+9=6×3

Simplify: 9+9=18

Addition: 18=18

The statement 18=18 is true, therefore we have our answer.

Answer: The second option is correct. 3 would be the correct number to substitute to make the equation correct.
