You invite your best friend Sheila out for a picnic on Thursday. Sheila tells you "If it rains, there is a 20% probability that I will come, but if it's sunny, there is an 80% probability that I will come." You check the weather and see that
there is a 40% chance of rain for that day. What is the overall probability that Sheila will attend your picnic? Explain
how you found your answer.

56%

Probably that it will rain and she goes + probably that it will be sunny and she goes

=     0.4 * 0.2     +           0.6*0.8

=          0.08      +              0.48

=   0.56

56% chance

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )

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.
