Answer:

\large\boxed{\large\boxed{Probability=1/256\approx  0.0039}}

Explanation:

Since, there are two possible outcomes for every toss (head or tail), the sample space for<em> a coin tossed 8 times</em> is 2×2×2×2×2×2×2×2 = 2⁸ = 256.

<em>Landing on heads all 8 times</em> is just one of the possible outcomes: HHHHHHHH ⇒ 1.

Hence, the <em>probability </em>is calculated from its own definition:

Probability = number of favorable outcomes / number of possible outcomes

  • Probability=1/256\approx  0.0039\text{         }\leftarrow answer

a^2+b*2=c^2 

a^2+2b=c^2&#10;&#10;  \text{Regroup terms} 

a^2=c^2-2b&#10;  \text{Subtract 2b from both sides} 

a=\pm \sqrt{c^2-2b}  \text{Take the square root of both sides}

Answer:

3:1

Step-by-step explanation:

We know that the number of students who prefer cheese AND vegetable pizza is 16 cheese + 2 vegetable = 18 combined

We also know that the number of students who prefer sausage AND pepperoni pizza is 3 sausage + 3 pepperoni = 6 combined

If we take the ratio between these figures, this ratio would be 18:6 (read as 18 to 6) which simplifies to 3:1 (read as 3 to 1).
