A regular six sided die and an eight equal segment spinner, numbered 1 to 8, are rolled/spun simultaneously. What are the odds i
kirill [66]

Answer:

1/3

Step-by-step explanation:

In statistics, the probability of both an event A and an event B happening is equal to the probability of A happening multiplied by the probability of event B happening.

Let's say spinning a prime number is event A and rolling a number ≤ 4 is event B.

There are 8 possibilities on an eight equal segment spinner, and there are 4 prime numbers between 1 and 8 (including 8), which are 2, 3, 5, and 7. This means that the probability of spinning a prime number is 4/8, or 1/2

There are 6 possibilities on a die, and there are 4 possibilities of rolling a 4 or less (1, 2, 3, 4). Therefore, the probability of rolling 4 or less on a die is 4/6, or 2/3

The probability of both of these happening can be calculated by multiplying these together, so 1/2 * 2/3 = 2/6 = 1/3

Answer:

0.3 galloons of water.

Step-by-step explanation:

We know that 1/5 galloons of water fills 2/3 of the bin.

So, we can write the following fraction:

\frac{\frac{1}{5}\text{ galloons}}{\frac{2}{3}\text{ bin}}

We want to find how many galloons will fill the entire bin or 1 whole bin. So, we can write the following proportion:

\frac{\frac{1}{5}\text{ galloons}}{\frac{2}{3}\text{ bin}}=\frac{x\text{ galloons}}{1\text{ bin}}

To find our answer, we need to solve for x.

So, let's cross-multiply. This yields:

\frac{2}{3}x=\frac{1}{5}

Multiply both sides by 3:

3(\frac{2}{3}x)=3(\frac{1}{5})

The left side simplifies. Multiply on the right:

2x=\frac{3}{5}

Now, multiply both sides by 1/2:

\frac{1}{2}(2x)=\frac{1}{2}(\frac{3}{5})

Simplify the left. Multiply on the right:

x=\frac{3}{10}

So, 3/10 of 0.3 of a gallon of water will fill the entire bin.

And we're done!
