Challenge No. 2: The joy park has four zones (water, fire, space, and desert zones). Due to safety matters, the park's management set a weekly schedule to maintain the park based on the zones. Thus, some zones will be open, while others will be closed for maintenance. The probabilities of closing vary from zone to zone based on visitors' numbers in its previous week. Accordingly, the probability of finding water zone under maintenance would be 30%, 30% for fire zone, 50% for space zone, and 10% for desert zone. Suppose a visitor is a lover of roller coaster rides. In that case, there is 0.3 probability that he will ride a water zone roller coaster, 0.25 probability that he will ride a fire 3 zone roller coaster, 0.35 probability that he will ride a space zone roller coaster, and 0.1 probability that he will ride a desert zone roller coaster. Find the probability of a visitor riding a space zone roller coaster? (4 marks)
