You randomly pick two numbers from 1 to 9 (including 1 and 9). if you could pick the same number twice and the first of the two numbers is odd and less than 5, then the probability that the sum of the two numbers is less than 5 is

Answer from: bqg464

-- If one number is odd and less than 5, then it must be either 1 or 3.The probability that it was chosen out of 9 numbers is (2/9) .
-- There is a 50/50 chance that the first number is 1 .If it is, and their sum is less than 5, then the second number is 1, 2, or 3 .The probability that it was chosen out of 9 numbers is (3/9) .
-- There is also a 50/50 chance that the first number is 3 .If it is, and their sum is less than 5, then the second number is 1 .The probability that it was chosen out of 9 numbers is (1/9)
If you are asking for the probability of the whole thing than your answer (rounded) would be 4.94%. Hope this helps!

Answer from: Quest

the answer is 200

step-by-step explanation:

this is a problem about poisson probabilities. i don't know if you've

already studied poisson distributions, or if you have a place to look

to read more about the subject.

here's how you can see a poisson distribution coming. when there are

a lot of events that may happen at any time (or any place), and when

you're counting how many of them happen at a particular time (or a

particular place), and each event is independent of the others, then

the result is a poisson distribution. this is roughly true for the

chocolate chips; one chip being in a cookie has only a small effect on

the probability that another chip will be in the cookie.

once you know you have a poisson distribution, you know a lot. there

is only one parameter to a poisson distribution, so if you know the

mean, you know everything. the form of the distribution is

probability of n chips = {[e^(-x)]*(x^n)} / (n! )

Answer from: Quest

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.

Need now max recorded the heights of 500 male humans. he found that the heights were normally distributed around a mean of 177 centimeters. which statements about max’s data must be true? a) the median of max’s data is 250 b) more than half of the data points max recorded were 177 centimeters. c) a data point chosen at random is as likely to be above the mean as it is to be below the mean. d) every height within three standard deviations of the mean is equally likely to be chosen if a data point is selected at random.

According to a study conducted in 2015, 18% of shoppers said that they prefer to buy generic instead of name-brand products. suppose that in a recent sample of 1500 shoppers, 315 stated that they prefer to buy generic instead of name-brand products. at a 5% significance level, can you conclude that the proportion of all shoppers who currently prefer to buy generic instead of name-brand products is higher than .18? use both the p-value and the critical-value approaches.
