1.Find the probability an observation is on a Thursday when the temperature is between 90 and 99 =

2/30  = 1/15 ≈  6.66% 

 

2.Find the probability an observation is on a Monday when the temperature is less than 90 =

1/30 ≈ 3.33%

 

3.Find the probability an observation is on a Friday when the temperature is greater than...???

 

4.Find the probability that the temperature is between 90 and 99, it will be a Thursday =

2/6  = 1/3 ≈  33.33%

 

5.Find the probability that if the temperature is between 110 and 120 and it will be a Sunday =

0 % ......this temperature  occurs only once.....on Friday
