The table shows the number of days that the maximum temperature was above 90º F in Death Valley National Park. The experimental probability that the maximum temperature will be greater than 90ºF on a given day in April is _16.67%.

Days above 90 degree F:
Days: 5 11 26 31
Month April May June July

For what month would you estimate the theoretical probability of a maximum temperature no greater than 90°F to be about 0.13?

Month	p above 90	p below 90

April	  5/30		  25/30
May	  11/31		  20/31
June	  26/30		   4/30
July	  31/31                           0

Can you simplfy the fractions in the right hand column and find the required month with p below 90 degrees about 0.13 ?
