A coin is tossed 8 times. Which of the following represents the probability of the coin landing on heads all 8 times?
ElenaW [278]

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
