Question

A vehicle arriving at an intersection can turn right, turn left, or continue straight ahead. The experiment consists of observing the movement of a single vehicle through the intersection. a List the sample space for this experiment. b Assuming that all sample points are equally likely, find the probability that the vehicle turns.

Answer 1

a) S = { Turn Left (L); Turn Right (R); Continue Straight (S) }

b) 2/3 or 0.667

Explanation:

a) There are three possible outcomes for this experiment, therefore the sample space is:

S = { Turn Left (L); Turn Right (R); Continue Straight (S) }

b) Since all outcomes are equally likely, and turning represents two out of the three possible outcomes, the probability that the vehicle turns is:

`P(turns) = (2)/(3)=0.667`
