A six- sided die is rolled once. Find the probability of the following events: a. Rolling the number 4 b. Rolling any number less than 3. c. Rolling a number 3 or more.
a. Rolling the number 4: Since there are 6 possible outcomes (numbers 1 to 6) and only 1 of them is a 4, the probability of rolling the number 4 is 1/6.
b. Rolling any number less than 3: There are two possible outcomes (numbers 1 and 2) out of six, so the probability of rolling any number less than 3 is 2/6, which simplifies to 1/3.
c. Rolling a number 3 or more: There are four possible outcomes (numbers 3 to 6) out of six, so the probability of rolling a number 3 or more is 4/6, which simplifies to 2/3.
