Which of the following best describes a longitudinal wave? Select one:

- A disturbance that moves the medium perpendicular to its line of travel.
- A disturbance that moves the medium along its line of travel.

1/4

Step-by-step explanation:

From the question:

Event A: Choosing shirts

Chang has 2 shirts: a white one and a black one.

Probability of choosing a white shirt = 1/2

Probability of choosing a black shirt = 1/2

Events B: Choosing a pair of pants

Chang also has 2 pairs of pants, one blue and one tan

Probability of choosing a blue pair of pants = 1/2

Probability of choosing a tan pair of pants = 1/2

Hence, the probability, if Chang gets dressed in the dark, that he winds up wearing the white shirt and tan pants?

= 1/2 × 1/2

= 1/4
