Angelique throws a different six-sided dice 120 times.
Alja [10]

The experimental probability of getting a multiple of 3 is \frac{3}{8}.

Given that, Angelique throws a different six-sided dice 120 times.

<h3>What is Probability in maths?</h3>

Probability denotes the possibility of something happening. It's a field of mathematics that studies the probability of a random event occurring. From 0 to 1, the value is expressed. Probability is a mathematical concept that predicts how likely occurrences are to occur.

We know that, Probability  of an  event=\frac{Number  of favourable  outcomes}{Total number  of outcomes}

Number of favourable outcomes =21+24=45

Total number of outcomes = 120

Probability of getting a multiple of 3=\frac{45}{120} =\frac{3}{8}

Therefore, the probability of getting a multiple of 3 is \frac{3}{8}.

(-1,1)
D0 means starting at the origin of Z in this case, so doing the same thing as always, multiply the scale factor -1/2 to the coordinate of Z giving you (-1,1) and this is the final answer because the origin is (0,0) so doesn’t change anything
