X^2 -5x -20=0
(x - 5/2)^2 -20 -25/4=0
(x-5/2)^2-105/4=0
(x -5/2 -(105)^1/2)(x -5/2 +(105)^1/2)=0
factors are (x -5/2 -(105)^1/2) and
(x -5/2 -(105)^1/2)

At Mike’s favorite coffee shop, the coffee of the day is either a dark roast, a medium roast, or a light roast. From past experi

Answer:

The correct option is d. 0.60

Step-by-step explanation:

Consider the provided information.

At Mike’s favorite coffee shop, the coffee of the day is either a dark roast, a medium roast, or a light roast.

The coffee being a light roast is 0.15 and the probability of the coffee being a dark roast is 0.25.

Pr(Light roast) = 0.15

Pr(Dark roast) = 0.25

We need to find the probability of the coffee of the day not being a light roast or a dark roast on the next day that Mike visits the coffee shop.

$Pr(\text{Not being light or dark roast}) =1-Pr(\text{light roast})-Pr(\text{dark roast})$

$Pr(\text{Not being light or dark roast}) =1-0.15-0.25$

$Pr(\text{Not being light or dark roast}) =1-0.40$

$Pr(\text{Not being light or dark roast}) =0.60$

Hence, the correct option is d. 0.60
