A volunteer ambulance service handles 0 to 5 service calls on any given day. I hè pPoBablitydistribution for the number of service calls is as follows:1234f (x)0.150.200.300.200.100.05Based on this probability distribution:• The volunteer ambulance service has achance of handling at least 3 calls on aparticular day.• The most likely number of service calls that the volunteer ambulance will handle on a given day iscalls. Note: Use the exact value of the mean in answering this question.Note: Input both of your answers rounded off to two decimal places.

Suppose you model a game of chance with a discrete probability distribution. Let X be the net amount of money or lost by the player. Let pX be the probability of the corresponding outcome. The three events are as follows: There is a 23% chance the player wins 7 dollars. there is a 38% chance the player loses 4 dollars. there is a 39% chance the player breaks even.

Your friend Phil, asks you what you think about a new scratch-off lottery game. It costs $10 to play this game, There are two outcomes for the game (win, lose) and the probability that a player wins a game is 60%. A win results in $15, for a net win of $5 ($15 minus the $10 paid to play). The probability distribution for x� (the amount of money a player wins or loses) in a single game is as follows:
