Question

There are $2$ red balls and $3$ blue balls and $5$ green balls in a bag. If a ball is drawn at a time, find the probability that it is blue green or red balls.

• A. $1/2$
• B. $8/10$
• C. $1$
• D. $0$

Answer 1

The correct option is C $1$

Total number of balls $=2+3+5=10$

Number of blue ,green and red balls$=2+3+5=10$

$P\left(A\right)=\frac{Numberoffavorableoutcomes}{TotalNumberofpossibleoutcomes}$

$\therefore P\left(A\right)=\frac{10}{10}=1$
