A coin is tossed 8 times. Which of the following represents the probability of the coin landing on heads all 8 times?
Answers
Answer:
Explanation:
Since, there are two possible outcomes for every toss (head or tail), the sample space for a coin tossed 8 times is 2×2×2×2×2×2×2×2 = 2⁸ = 256.
Landing on heads all 8 times is just one of the possible outcomes: HHHHHHHH ⇒ 1.
Hence, the probability is calculated from its own definition:
Probability = number of favorable outcomes / number of possible outcomes
Answer:
1/256

The product of 3.68 can be obtained from the following expressions:
B. 4.6 × 8 D. 4.6 × 0.8
How to determine the expressions of a product?
Let's calculate the products and see which expressions result in a product of 3.68.
B. 4.6 × 8 = 36.8
D. 4.6 × 0.8 = 3.68
They are explained below:
Option B (4.6 × 8) results in a product of 36.8, which is not equal to 3.68.
Option D (4.6 × 0.8) results in a product of 3.68, which matches the desired value.
Therefore, the expressions that have a product of 3.68 are option D: 4.6 × 0.8.

35-10=15 and then: x-35
So we will make the proportion:
4 : 10 = (x-35) : 15
4 * 15 = 10(x-35)
60=10 x- 350
10 x =410
x = 41%
