Answer:

Step-by-step explanation:

 3x -  y  = -1

<u>-3x + 3y = 27  </u>

       2 y = 26

When adding, 3x + (-3x) = 0

3y - y = 2y

27- 1 = 26

The probability that both of two tossed coins will come down heads is _____. 1/4 1/8 1/16
Elza [17]
<span>The probability of getting heads with both coins being tossed is 1/4. The probability of getting a heads on one coin is 50% (or 1/2) since there is only two possible outcomes, heads or tails. When you factor in two coins, you have to multiply the probabilities together, 1/2 x 1/2, which is how you get the answer of 1/4 or 25%. Another way to reinforce this is that there are 4 possible outcomes to the flips. You could get a heads-heads, tails-heads, heads-tails, or tails-tails. Getting the heads-heads result is 1 out of 4 or 1/4 (25%).</span>
