Hot air balloon travels 18 miles in 3 hour. At this rate how many miles will the hot air balloon travel in 3/4 hour?
seropon [69]
You can figure out how many miles per hour it travels by dividing 18/3. This gives us the answer of 6. 3/4 = 0.75 so we can multiply 6 * 0.75 to get 4.5 as our final answer. It will travel 4.5 miles in 3/4 of an hour.

What is the probability of rolling a 3 on two consecutive rolls of a fair 6-sided die?
Ad libitum [116K]

Answer:

\frac{1}{36} chance

Step-by-step explanation:

Each time you roll a die, you have a \frac{1}{6} chance of rolling a 3. It's even rarer to roll two 3s in a row, and to find a consecutive probability, we have to multiply the two probabilities. In this case, both probabilities are \frac{1}{6}.

\frac{1}{6}\cdot\frac{1}{6}=\frac{1}{36}

Hope this helped!
