\( P(G | \overline{H}) \) is the conditional probability of \( G \) given \( \overline{H} \).
\( P(G \cap \overline{H}) \) is the probability that both \( G \) and \( \overline{H} \) occur.
\( P(\overline{H}) \) is the probability that \( H \) does not occur.
\[ P(G | \overline{H}) = \frac{P(G \cap \overline{H})}{P(\overline{H})} = \frac{1}{3} \]If the probability distribution is given by:
| X | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
|---|---|---|---|---|---|---|---|---|
| P(x) | 0 | k | 2k | 2k | 3k | k² | 2k² | 7k² + k |
Then find: \( P(3 < x \leq 6) \)
If \(S=\{1,2,....,50\}\), two numbers \(\alpha\) and \(\beta\) are selected at random find the probability that product is divisible by 3 :
