1. A jar contains 100 gummy bears: 50 ordinary candies, and 50 cannabis edibles. Of the ordinary candies, 40 are red and 10 are green. Of the cannabis edibles, 20 are red, and 30 are green. A gummy bear is drawn at random from the jar, in such a way that each gummy bear is equally likely to be the one drawn. What is the probability that the drawn gummy bear is a cannabis edible, conditional on it being red?

Solutions

Expert Solution

P(cannabis edible | being red) = P(cannabis edible and being red) / P(being red)

= (20/100) / ((20+40)/100)

= 20/60

= 1/3 or 0.3333

A piston–cylinder device contains 5 kg of steam at 100°C with a quality of 50 percent. This steam undergoes two processes as follows: (1-2) Heat is transferred to the steam in a reversible manner while the temperature is held constant until the steam exists as a saturated vapor.(2-3) The steam expands in an adiabatic, reversible process until the pressure is 15 kPa. Sketch these processes with respect to the saturation lines on a single TS diagram and determine the heat...
