Question

Bag contains $100$ tickets bearing numbers $1-100$. A ticket is taken out randomly, find the probability getting of a even numbered ticket.

• A. $0.5$
• B. $0.4$
• C. $1.0$
• D. $0.05$

Answer 1

The correct option is A $0.5$

Total number of tickets, $n\left(S\right)=100$

Favorable outcomes for even number, $n\left(E\right)=50$

The probability getting of an even numbered ticket, $\frac{n\left(E\right)}{n\left(S\right)}=\frac{50}{100}=0.5$
