The answer is false.

Exactly <em>1 </em>tail would mean the probability is 1/2.

When tossing 2 coins the probability of getting one tail is:

P(HT)+P(TH)

P(HT)=(1/2)^2=1/4 and P(TH)=(1/2)^2=1/4

P(HT or TH)=1/4+1/4=2/4=1/2

Answer:

  a.  (-1/2, 5)

Step-by-step explanation:

The coefficients of x have opposite signs, so the x-terms can be eliminated by adding the two equations.

  (2y -12x) +(3y +12x) = (16) +(9)

  5y = 25 . . . . . . simplify

  y = 5 . . . . . . . . .divide by 5

This matches only answer choice A.

__

<em>Check</em>

The other part of answer choice A is x = -1/2. We can test this to make sure it works:

  2(5) -12(-1/2) = 16

  10 + 6 = 16 . . . . . . true, the selected answer works OK
