What is the probability that a dice rolls a 1, three times in a row.
lisov135 [29]

Answer:

1/216 or 0.0046

Step-by-step explanation:

Rolling a '1' one time has a probability of 1/6.  Rolling a die three times and getting a '1' each time is an independent event, meaning that no roll affects the probability of a '1' happening on any other roll.  When calculating probability of independent events, multiply them together.  So the probability of a '1' three times in a row is...

(1/6)(1/6)(1/6) = 1/216 or 0.0046

A car travels 1/6 of the distance between two cities in 3/5 of an hour. At this rate, what fraction of the distance between the
Delvig [45]

<u>Answer:</u>

\frac{5}{18}

<u>Step-by-step explanation:</u>

Distance traveled by a car between two cities = 1/6 distance

Time taken to travel between the two cities = 3/5 hours

Therefore, to find how much of the distance the car can travel in 1 hour, we need to divide the given distance by the given time to get:

(\frac{1}{6}) ÷ (\frac{3}{5})

Change the later fraction to its reciprocal to solve:

\frac{1}{6} × \frac{5}{3} = \frac{5}{18}

Therefore, in one hour, the car can travel 5/18 of the distance.
