Question

A coin is tossed 200 times and head appeared 120 times. The probability of getting a head in this experiment is
a. 2/5
b. 3/5
c. 1/5
d. 4/5

Answer 1

$\text{P("getting head")}~=~\dfrac{\text{number of times head appeared}}{\text{number of times the experiment is done}}\\~\\=\dfrac{120}{200}\\~\\=\dfrac{3}{5}$

Answer 2

P(getting head ) = 120 / 200 = 3/ 5
