The following table sumriarizes measurements of measuring the Temperature versus the pressure in a particular lab experiment. - Event A represents the situation that the pressure is 330 - Event B represents the situation that the pressure is 335 - Events C represents the situation that the Temperature is low Events D represents the situation that the Temperature is high Pressure 320 325 330 335 Temperature Condition Low High 23 50 45 18 63 40 75 45 Find the number of observations of the following events: (a) (A'N CUD (b) (AN B') nc (c) (AUB) NC (d) (AUD')
