# A coin is tossed 500 times and we get

Question:

A coin is tossed 500 times and we get
head: 285 times, tail: 215 times.
When a coin is tossed at random, what is the probability of getting
(ii) a tail?

Solution:

Total number of tosses =  500
$P($ getting a head $)=P(E)=\frac{\text { Number of heads coming up }}{\text { Total number of trials }}=\frac{285}{500}=0.57$
$P$ (getting a tail) $=P(F)=\frac{\text { Number of tails coming up }}{\text { Total number of trials }}=\frac{215}{500}=0.43$
