An investor is considering 3 stocks (A, B, and C) that could potentially rise in price soon. The probability that stock A will rise in price is 0.3 while that of B and C are 0.7 and 0.9 respectively.

Assume these events are independent.

Hint: Draw a probability tree/tree diagram. Do not round calculation results.

What is the probability that

1. all 3 stocks will rise in price? Correct
2. none of the 3 stocks will rise in price? Incorrect
3. not all 3 stocks will rise in price? Correct
4. only stock C will rise in price? Incorrect
5. only stocks A and B will rise in price? Correct
6. only stock B will not rise in price? Correct
7. at least one stock will rise in price? Incorrect
8. no more than two stocks will rise in price?
9. only one stock will rise in price? Incorrect
10. stock A will not rise in price given both C and B rise in price?
