Question
Two coins are tossed simultaneously. Write the sample space (S) and expected sample points in the given events by completing the activity.
- Event A: to get at least one head.
- 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}`.
Solution
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}.
