Does the following list represent a complete probability model? Explain.
P(red) = 16 , P(yellow) = 13 , P(blue) = 112 , and P(green) = 12

Yes

Step-by-step explanation:

The sum of probabilities listed on probability model must be equal to 1

Total = 16+13+112+12

= 153

P(red)+P(yellow)+P(blue)+P(green) = 16/153+13/153+112/153+12/153

= (16+13+112+12)/153

= 153/153

= 1

D

Step-by-step explanation:

1/6+ 1/3+ 1/12 + 1/2= 13/12 so it is greater than 1

and D says Yes: the sum of the probabilities is greater than 1.

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
