- In the pine tree forest, the probability that a randomly chosen tree is a high producer, that is, it has more than 60 cones, is 0.46.
- If a forester selects trees until he finds one that is a high producer, what is the probability that he selects more than 2 trees?
- Suppose the forest contains 2000 trees, use a normal approximation to find the probability that fewer than 950 of them are high producers.
- Use software ( a calculator) to find the probability in b exactly. Compare your results.

you have chosen a binomal tree to model the price dynamic of a
stock. the probability of an up move is 0.60. if the stock mives
up, it earns a 5% return. if the stock moves down, it loses a 5%
return. The current stock price is $100.
A.) compute the possible stock prices after two periods (based
on the binomial tree for the stock price dynamic change).
B.) compute the corresponding probabilities for each possible
price.
C.) compute the...

What is the probability that a randomly chosen positive integer
not exceeding 1000, is a power of another integer. For example,
64=82 or 27=33 are powers but 55 or 24 are not powers.

The latest political survey in the United States indicates that,
of randomly chosen citizens, the probability that they are liberal
is 0.22, the probability that they are conservative is 0.55, and
the probability that they are neither one nor another is 0.24.
Assuming these probabilities are accurate, answer the following
questions regarding the group of 10 randomly chosen Americans. (16
point)
What is the probability that four are liberal?
What is the probability that neither is conservative?

A researcher crossed several randomly chosen pink tree peonies,
Paeonia suffruticosa, to test a genetic model of inheritance. She
expected to see red:pink:white offspring colors in the ratio of
12:3:1. Below are the observed color proportions of the 83 plants
in the study:
Observed Proportions of Progeny Colors
Red 0.747, Pink 0.205, White 0.048
Conduct a hypothesis test to determine if the observed
proportions significantly differ from the expected ration. Given:
critical = 5.99
