Which of the following is a pair of events which are dependent on one another? a. observing rainfall in two different cities b. drawing a pair of cards from a deck c. putting on a pair of pants and a shirt without looking at them d. rolling two dice with the same number of sides

b. drawing a pair of cards from a deck.

Explanation:

These are the pair of events that are dependent on each other. Two events are considered to be dependent if the outcome or occurrence of the first affects the outcome or occurrence of the second. In other words, if the first event happens, the probability of the second one is affected. In this case, the probability of chosing a card is out of 52 (the number of cards contained in a deck). However, after the first card is removed, the probability of the second one is now calculated out of 51.
