# If two coins are tossed, find the probability of event getting head on both the coins - Algebra

Sum

If two coins are tossed, find the probability of event getting head on both the coins

#### Solution

Sample space,

S = {HH, HT, TH, TT}

∴ n(S) = 4

Let A be the event of getting head on both the coins.

∴ A = {HH}

∴ n(A) = 1

∴ P(A) = ("n"("A"))/("n"("S"))

∴ P(A) = 1/4
