Question

The numbers 2, 4, 6, 8, 10, 12 are on the surface of one die. If this die is rolled once, then complete the activity to find probability of getting a perfect square number on upper face.

Activity:

S = `{square}` ∴ n(S) = `square`

Condition for event B: getting a perfect square number on the upper surface of that die.

B = `{square}`   ∴ n(B) = `square`

P(B) = `"n(B)"/"n(S)" = square/6`

= `square`.

Answer 1

S = {\[\boxed{2, 4, 6, 8, 10, 12}\]} ∴ n(S) = \[\boxed{6}\]

Condition for event B: getting a perfect square number on the upper surface of that die.

B = \[\boxed{4}\] ∴ n(B) = \[\boxed{1}\]

P(B) = `"n(B)"/"n(S)"` = \[\frac{\boxed{1}}{6}\]

= \[\boxed{\frac{1}{6}}\].
