3 coins tossed at a time what is the probablity of getting at most 2 heads
Read Solution (Total 6)
-
- atmost 2 heads means we can have every combination except HHH
so the answer will be atmost 2 head=7/8. - 10 years agoHelpfull: Yes(3) No(0)
- favorable outcome=1- non favorable
here only HHH is non favorable
total outcomes= 2^3
ans = 1-1/8= 7/8 - 10 years agoHelpfull: Yes(1) No(0)
- chance of getting at most 2 heads is(HHT,HTH, HTT, TTT, THH,THT,TTH,)
SO PROBABILITY IS 7/6^3 - 10 years agoHelpfull: Yes(0) No(2)
- probability would be 3/8
- 10 years agoHelpfull: Yes(0) No(0)
- total outcome=8 {HHH,HHT,HTH,HTT,TTT,TTH,THT,THH}
ans favorable outcome={oucome in which no head of more than two head comes}
so the answer is =6/8 - 10 years agoHelpfull: Yes(0) No(1)
- P(of getting at most two heads)=¾
- 9 years agoHelpfull: Yes(0) No(0)
