Here S = {HHH, HHT, HTH, THH, TTH, THT, HTT, TTT}
(i) Favourable number of elementary events = 3 [HHT, HTH, THH]
∴ P (two heads) = 3/8
(ii) Favourable number of elementary events = 4 [HHH, HHT, HTH, THH]
When three coins are tossed, the sample space is given by
S = {HHH, HHT, HTH, HTT, THH, THT, TTH, TTT}
Accordingly,
A = {HHH}
B = {HHT, HTH, THH}
C = {TTT}
D = {HHH,...
When three coins are tossed, the sample space is given by
S = {HHH, HHT, HTH, HTT, THH, THT, TTH, TTT}
(i) Two events that are mutually exclusive can be
A: getting no...
When two coins are tossed simultaneously, the possible outcomes are(H, H),(H, T),(T, H),(T, T) which are all equally likely. Here (H, H) means head up on the first coin (say on Rs.1) and...
Elementary events associated to random experiment of tossing three coins are
HHH , HHT, HTH ,THH , HTT,THT,TTH ,TTT
Total number of elementary events = 8.
(i) The event getting all heads is said to...
Total number of possible outcomes = 36
(i) Outcomes favourable to given event are: (4, 6), (5, 5), (5, 6), (6, 4), (6, 5), (6, 6)
Number of favourable outcomes = 6
