Hannah has a chicken coop with six hens. Let [tex]$X$[/tex] represent the total number of eggs the hens lay on a random day. The distribution for [tex]$X$[/tex] is given in the table below:

\begin{tabular}{|c|c|c|c|c|c|c|c|}
\hline
\begin{tabular}{c}
Number of \\
Eggs
\end{tabular} & 0 & 1 & 2 & 3 & 4 & 5 & 6 \\
\hline Probability & 0.02 & 0.03 & 0.07 & 0.12 & 0.30 & 0.28 & 0.18 \\
\hline
\end{tabular}

What is the probability that the hens lay more than two eggs?

A. 0.07
B. 0.12
C. 0.88
D. 0.95



Answer :

To find the probability that the hens lay more than two eggs, we need to sum the probabilities of the outcomes where the number of eggs is greater than two.

From the distribution table, these outcomes and their respective probabilities are:

- 3 eggs: [tex]\(P(X = 3) = 0.12\)[/tex]
- 4 eggs: [tex]\(P(X = 4) = 0.30\)[/tex]
- 5 eggs: [tex]\(P(X = 5) = 0.28\)[/tex]
- 6 eggs: [tex]\(P(X = 6) = 0.18\)[/tex]

To find the total probability for [tex]\(X\)[/tex] being greater than 2, we add these probabilities together:

[tex]\[ P(X > 2) = P(X = 3) + P(X = 4) + P(X = 5) + P(X = 6) \][/tex]

[tex]\[ P(X > 2) = 0.12 + 0.30 + 0.28 + 0.18 \][/tex]

Summing these values:

[tex]\[ P(X > 2) = 0.12 + 0.30 + 0.28 + 0.18 = 0.88 \][/tex]

Thus, the probability that the hens lay more than two eggs is:

[tex]\[ \boxed{0.88} \][/tex]
