Answer 1

Step-by-step explanation:

Tickets = 200

Tickets with prizes = 50

Tickets with blank prizes = 150

Probability =

150 ÷ 200

15 ÷ 20

3 ÷ 4

0.75

$\huge{\fcolorbox{black}{pink}{\fcolorbox{pink}{black}{\bf{\color{pink}{⚘ÃñSwÉr⚘}}}}}$

Total number of lottery tickets = 200

Number of blank tickets = 200-50 = 150

We know, probability is given by :

$\bf \large{ \frac{no. \: of \: possible \: outcomes}{total \: no. \: of \: outcomes} }$

Therefore, probability of getting a blank ticket :

$\bf \large{ = > \frac{no. \: of \: blank \: tickets}{total \: no. \: of \: tickets} }$

$\bf \large{ = > \frac{150}{200} }$

$\bf \large{ = > \frac{3}{4} }$

hope this helps dear
