Problem

This table provides data on the daily maximum temperatures in Barcelona during summer.

Summer Temperatures<br>in Barcelona	Month
	June	July	Aug
Mean days max. $\ge 40^\circ\text{C}$	0.3	1.2	0.7
Mean days max. $\ge 35^\circ\text{C}$	3.0	5.8	5.3
Mean days max. $\ge 30^\circ\text{C}$	9.4	12.3	12.0

a. Estimate the probability that on an August day in Barcelona, the maximum temperature will be: -

35^\circ\text{C}

or higher - less than

30^\circ\text{C}

. b. Estimate the probability that on any summer day in Barcelona, the temperature will be

30^\circ\text{C}

or higher. c. It is a

40^\circ\text{C}

summer day in Barcelona. Estimate the probability that the month is July.
