I have the right solutions for the questions but i need to know how to calculate it! The bold answer is always the correct answer.

The probability that the share of the mountain railroad company "Sunburn" will rise in the next month is 70%. The probability that the average daily maximum temperature in the same month will be greater than 25C is 60%. Assume that the probability of both events occurring together at the same time is 52%.

After one month, it shows that the average daily maximum temperature was 24C. What is the probability that Share fell.

a) 24%

b) 47%

c) 55% (correct solution, but how is the calculation done?)

d) 66%

e) 87%
