<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>

10, 12.
Find the number in between 10 and 12.
= 11
Answer:
Step-by-step explanation:
x² + y² = 81
x + y = √81
x + y = 9
x ≥ 9
y ≤ 9
X + 2 1/2 - 3/4 = 5 1/4 To find x, go backwards in the equation.
5 1/4 + 3/4 = 6 cups
6 - 2 1/2 = 3 1/2 cups
x = 3 1/2 cups
