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

Summer temperatures in Barcelona	June	July	August
Mean days with maximum $\geq40^\circ\text{C}$	0.3	1.2	0.7
Mean days with maximum $\geq35^\circ\text{C}$	3.0	5.8	5.3
Mean days with maximum $\geq30^\circ\text{C}$	9.4	12.3	12.0

(1) Estimate the probability that, on an August day in Barcelona, the maximum temperature will be

35^\circ\text{C}

or higher, and the probability that it will be less than

30^\circ\text{C}

. (2) Estimate the probability that, on any summer day in Barcelona, the maximum temperature will be

30^\circ\text{C}

or higher. (3) It is a

40^\circ\text{C}

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