Answer:
0.667 is the probability that Billy will roll a 3 or higher.
Step-by-step explanation:
We are given the following in the question:
E: Rolling of a six-sided die
The sample space for the given event is
S: {1, 2, 3, 4, 5, 6}
We have to find the probability that Billy will roll a 3 or higher.
[tex]\text{Probability} = \displaystyle\frac{\text{Number of favourable outcomes}}{\text{Total number of outcomes}}[/tex]
P( roll a 3 or higher) =
[tex]\displaystyle\frac{n(\text{ 3 or higher)}}{6} = \frac{4}{6} = \frac{2}{3} = 0.667[/tex]
Thus, 0.667 is the probability that Billy will roll a 3 or higher.
