Let X represent the number of homes a real estate agent sells during a given month. Based on previous sales records, she estimates that Upper P (0 )equals 0.60, Upper P (1 )equals 0.23, Upper P (2 )equals 0.11, Upper P (3 )equals 0.04, Upper P (4 )equals 0.02, with negligible probability for higher values of x. a. Explain why it does not make sense to compute the mean of this probability distribution as (0 plus 1 plus 2 plus 3 plus 4 )divided by 5 equals 2.0. b. Find the correct mean and interpret.

The mean is 0.65

Step-by-step explanation:

See the attachment for step by step solution and interpretation.

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
