Answer 2

Step-by-step explanation:

Given:

8 blue pencil

17 red pencil and

5 yellow pencil

8+17+5=30

we get

total outcome =30

a. blue pencil

Given

8 blue pencil

since Favourable outcome =8

P(8 blue pencil)=Favourable outcome/total outcome

8/30 =3.57

b. Not a red pencil

since total outcome =30

Given.

8 blue pencil and 5 yellow pencil

8+5=13

therefore favourable outcome =13

P(not a red pencil)= Favourable outcome /

Total outcome

=13/30=0.4333...
