alleryA die is rolled and E is the event of getting a multiple of 7. The event E is best described as:
AAn impossible event, since it can never occur
BA sure event, since it occurs on every roll
CA simple event, having one sample point
DA compound event with two sample points
Answer & Solution
Correct answer: A. An impossible event, since it can never occur
1. A die shows only 1, 2, 3, 4, 5 or 6, and none of these is a multiple of 7.
2. So the event E corresponds to the empty set, which can never occur.
3. An event equal to the empty set is called an impossible event.
