Answer 1

Answer:

the answer is

$\frac{9}{25}$

Step-by-step explanation:

total outcome of all pencils are 25

but our possible outcome is either red or blue which means either 5 or 4

1. Probability=possible outcome/total outcome

P(either red or blue)=

$\frac{5}{25} + \frac{4}{25} = \frac{9}{25}$
