Easy Mathematics

In a farming simulation game, an animal has equal chance to produce a product at anytime between 30 and 40 second after you fed them. a) When you fed an animal, determine the probability that you receive 2 product after 1 minute 10 seconds. b) When you fed 5 animals, what is the expected number of product you will receive in 38 seconds? c) At the beginning of a game, a player has 20 chickens which produce eggs, each player is required to receive 32 eggs within t seconds, otherwise he loses the game. i) When t = 75, determine the probability that the player loses the game. ii) You should ensure that each player has 95% of winning chance, determine the least integer value of t that satisfies the requirement.
