Solution: We are given that the population of Virginia is 8 million.
Let x be the population of Nevada.
We are given population of Virginia is 2.8 million less than 4 times the population of Nevada.
The first step is to on both sides.
add 2.8
The second step is to on both sides.
divide 4
The population of Nevada is million.
2.7
Answer:
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
