Consider the following data: x −4−4 −3−3 −2−2 −1−1 00 P(X=x)P(X=x) 0.20.2 0.30.3 0.10.1 0.20.2 0.20.2 Copy Data Step 4 of 5 : Find the value of P(X≥−1)P(X≥−1). Round your answer to one decimal place.

Step-by-step explanation:

We are given the following in the question:

x:                −4       −3       −2      −1       0

P(X=x):        0.2      0.3      0.1     0.2     0.2

We have to evaluate

Since it is a discrete probability distribution as

We can evaluate the probability as:

Thus, 0.4 is the require probability.

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.  

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.
