	The temperature in June		2005-12-12
		Farina pose la question : Question: Hi, I was having problem doing this problem. Question: Suppose the temperature during June is normally distributed with the mean= 20 degrees C and standard deviation= 3033 deg. A i the event that temperature is between 21.11 deg C. B is the event that the temperature is over 25Ged C. Event C is the temperature is below freezing point. Find the following probabilities: A) P(A) b) P(B) C) P(C) D) P(C given B) E) P(neither A nor B) F) find the expected number of days in June when event B will occur. I know how to find questions A-D I am only having problem with question E and F. Can you please help me. Thank You. Penny Nom lui répond.
