There are $600$ students in a high school junior class. Of these $600$ students, $350$ regularly wear a watch to school, $325$ regularly wear earrings, and $300$ regularly wear a watch *and* earrings. Using this information, answer each of the following questions.
Let $W$ be the event that a randomly selected junior regularly wears a watch and $E$ be the event that a randomly selected junior regularly wears earrings.
**What is $P(W)$, the probability that a junior wears a watch?** [[☃ input-number 1]]
**What is $P(E)$, the probability that a junior wears earrings?** [[☃ input-number 2]]
**What is $P(W\text{ and }E)$, the probability that a junior wears a watch *and* earrings?** [[☃ input-number 3]]
**What is $P(W\text{ or }E)$, the probability that a junior wears a watch *or* earrings?** [[☃ input-number 4]]
