[tex] \frac{1}{3}\\\\
\frac{2}{3}\\\\
\frac{0}{12}[/tex]
Step-by-step explanation:
Red blocks = 4, White blocks = 4, Blue blocks = 4, Green blocks = 0
Total blocks = 4 + 4 + 4 = =12
1)
Probability of picking a red block
[tex] =\frac{No. \: of\: red\: blocks}{Total\: blocks}
=\frac{4}{12}
=\frac{1}{3}[/tex]
2)
Probability of not picking a red block
[tex] =\frac{No. \: of\: white\: and \: blue\: blocks}{Total\: blocks} \\\\
=\frac{4+4}{12}
=\frac{8}{12}
=\frac{2}{3}[/tex]
3)
Probability of picking a green block
[tex] =\frac{No. \: of\: green \: blocks}{Total\: blocks}
=\frac{0}{12}[/tex]
