Three coins are tossed together. Find the probability of getting no tails
Advertisements
उत्तर
When 3 coins are tossed together,
Total no. of possible outcomes = 8 {HHH, HHT, HTH, HTT, THH,THT, TTH, TTT}
Probability of an event =`"No.of favorable outcomes"/"Total no.of possible outcomes"`
E ⟶ getting no tails
No. of favourable outcomes = 1 {HHH}
Total no. of possible outcomes = 8
P(E) =1/8
