Two coins are tossed simultaneously. Write the sample space (S) and expected sample points in the given events by completing the activity.

  1. Event A: to get at least one head.
  2. Event B: to get no head.

Activity: Let ‘S’ be the sample space, when two coins are tossed simultaneously.

∴ S = `{square, HT, TH, square}`

i. Event A: to get at least one head.

∴ A = `{HH, square, TH}`

ii. Event B: to get no head.

∴ B = `{square}`.

Activity: Let ‘S’ be the sample space, when two coins are tossed simultaneously.

∴ S = {HH, HT, TH, TT}

Event A: to get at least one head.

∴ A = {HH, HT, TH}

Event B: to get no head.

∴ B = {TT}.
