Question

Three unbiased coins are tossed together.what is the probability of getting all heads

Answer 1

3 coins tossed then
Outcomes : TTT ,TTH,THH,THT, HHH, HHT, HTT, HTH.
So the probability of getting all heads
= 1/8

Answer 2

Answer:

$\frac{1}{8}$

Step-by-step explanation:

Three unbiased coins are tossed

Possible events :

(HHH)

(HHT)

(HTH)

(THH)

(HTT)

(THT)

(TTH)

(TTT)

Total outcomes = 8

Favorable outcome= {HHH}=1

So,  probability of getting all heads = $\frac{\text{Favorable outcomes}}{\text{Total outcomes}}$

                                                           = $\frac{1}{8}$

Hence  the probability of getting all heads is $\frac{1}{8}$
