Question

two coins are tossed simultaneously the probability of getting at most one head is
a ) 14
b ) 34
c ) 12
d ) 14​

Answer 1

Option B is correct

Step-by-step explanation:

Two coin tossed

Total sample space = {HH, HT, TH, TT}

Sample space for getting atmost one head = {TT, TH, HT}

P(s) = 3/4

Answer 2

Answer:

When two coins are tossed the results are (HH,HT,TH,TT)

Total no. of outcomes =4

1) Exactly one head = only two cases are (HT,TH)

=

4

2) At least one tail = There are three cases (HT,TH,TT)

=

4

3) No. tail = only one case (HH) =

4

4) Atmost one head =three cases (HT,TH,TT)

=
