Question
Two coins are tossed simultaneously. Complete the following activity to write the sample space and the given events A and B in the set form:
Event A: To get at least one head.
Event B: To get no head.
Activity:
Two coins are tossed simultaneously.
∴ Sample space is
S = `{square, HT, TH, square}`
Event A: To get at least one head.
∴ A = `{square, HT, TH}`
Event B: To get no head.
∴ B = `{square}`
Solution
Two coins are tossed simultaneously.
∴ Sample space is
S = {\[\boxed{HH}\], HT, TH, \[\boxed{TT}\]}
Event A: To get at least one head.
∴ A = {\[\boxed{HH}\], HT, TH}
Event B: To get no head.
∴ B = {\[\boxed{TT}\]}

Activity : If two coins are tossed simultaneously
∴ s = {`square , "HT","TH", square`}
1) Event A : at least getting one head.
∴ A = {`"HH" , square , "TH"`}
2) Event B : to get no head.
∴ B = {`square`}
