Here are the outcomes
HHH,HHT,HTH,HTT,THH,THT,TTH,TTT
Total no: of outcome = 8
no :of heads = 1
Probability = No:of times head occurred ÷ Total no: of outcomes
= 1 ÷ 8
= 1 / 8
HHH,HHT,HTH,HTT,THH,THT,TTH,TTT
Total no: of outcome = 8
no :of heads = 1
Probability = No:of times head occurred ÷ Total no: of outcomes
= 1 ÷ 8

please tell me which is the right answer?
so the occurence of 3 heads is one time
so 1/8
so the answer is 1/8?
ok
yea
thanks maria

the outcomes are:
HHH,HTT,TTT,HTH,THT,HHT,TTH,THH
therefore 8 total outcomes.
probability =favourable outcomes/total no of outcomes
favourable outcomes of 3 heads =1
The probability of getting 3 heads=1/8
HHH,HTT,TTT,HTH,THT,HHT,TTH,THH
therefore 8 total outcomes.
probability =favourable outcomes/total no of outcomes
favourable outcomes of 3 heads =1
The probability of getting 3 heads=1/8
No ,maria how can tht be

ya 1/6 is right answer
but there should be two more outcomes
