Question

Three coins are tossed once. Find the probability of getting: 3 tails

✓

Answer

When three coins are tossed then total outcomes, S = {HHH, HHT, HTH, THH, TTH, HTT, TTT, THT}
Where s is sample space and here n(S) = 8
Let A be the event of getting 3 tails
n(A) = 1
P(getting 3 tails) = P(A) = $\frac{\mathrm{n}(\mathrm{A})}{\mathrm{n}(\mathrm{S})}=\frac{1}{\mathrm{8}}$
