Answer: outcomes in sample space = 12, outcomes involve choosing a blue marble =4.
Step-by-step explanation:
Choices for numbers = 4
Choices for marbles =3
By Fundamental counting principle,
Outcomes in sample space = (Choices for numbers) x (Choices for marbles)
= 4x 3
=12
Hence, outcomes in sample space = 12
Number of outcomes involved for blue marble = (Choices for numbers) x ( choice of marble (1))
= 4 x 1 =4
Hence, outcomes involve choosing a blue marble =4.
