# 4.(a)  In a certain lottery  $\small 10,000$  tickets are sold and ten equal prizes are awarded. What is the probability of not getting a prize if you buy (a) one ticket

H Harsh Kankaria

Given, Total number of tickets sold = 10,000

Number of prizes awarded = 10

(a) If one ticket is bought,

P(getting a prize) =   $\frac{10}{10000} = \frac{1}{1000}$

$\therefore$ P(not getting a prize) = 1 - P(getting a prize)

$1- \frac{1}{1000} = \frac{999}{1000}$
