Question

For one die, which option correctly describes the Certain / Sure event “Number \(\leq 6\)”

Options

• It contains exactly one outcome, \(A = \{6\}\), with \(n = 1\)

• It contains every outcome, \(A = S = \{1, 2, 3, 4, 5, 6\}\), with \(n = 6\)

• It contains only \(\{1, 2, 3, 4, 5\}\), with \(n = 5\)

• It contains no outcome, \(A = \{\} = \phi\), with \(n = 0\)

Answer 1

Every possible number on a die is at most 6. Thus, the event contains every outcome and satisfies \(A = S\).
