Answer:

2n + 3

Step-by-step explanation:

To find twice a number, we can do it in several ways:

  • The first is adding the number twice, in this case the number is n, so the operation would be n + n = 2n.
  • The other way is to multiply the number by 2, so 2 * n = 2n.

Then you have to add 3 to the result. The previous result was 2n so now we get:

2n + 3

Mandvil has one standard quarter and one special quarter with a Head on both sides. He selects one of these two coins at random,
Lana71 [14]

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%.
