Total number of socks = 4 + 3 + 5 = 12

We want same color socks

So we want, 2 white or 2 blue or 2 grey socks

$\begin{gathered}{\bold{\sf{Probability \: of \: 2nd \: sock \: being \: white \: = \: \frac{3}{11}}}} \\ \end{gathered}$

$\begin{gathered}{\bold{\sf{➙ \: \: \: \: \: \frac{4}{12} \: \: × \: \: \frac{3}{11} \: \: = \: \: \frac{1}{11}}}} \\ \end{gathered}$

$\begin{gathered}{\bold{\sf{➙ \: \: \: \: \: \frac{3}{12} \: \: × \: \: \frac{2}{11} \: \: = \: \: \frac{1}{22}}}} \\ \end{gathered}$

$\begin{gathered}{\bold{\sf{➙ \: \: \: \: \: \frac{5}{12} \: \: × \: \: \frac{4}{11} \: \: = \: \: \frac{5}{33}}}} \\ \end{gathered}$

$\begin{gathered}{\bold{\sf{➙ \: \: \: \: \: \: \frac{1}{11} \: \: + \: \: \frac{1}{22} \: \: + \: \: \frac{5}{33} \: \: = \: \: \frac{19}{66}}}} \\ \end{gathered}$

Answer 2

Plants are called autotrophs because they can use energy from light to synthesize, or make, their own food source. Many people believe they are “feeding” a plant when they put it in soil, water it, or place it outside in the Sun, but none of these things are considered food. Rather, plants use sunlight, water, and the gases in the air to make glucose, which is a form of sugar that plants need to survive. This process is called photosynthesis
