I. Implement Bingo GameProblem DescriptionIn the game of Bingo, numbers are chosen at random from a set between 1 and 75 inclusive. The numbers in the range:· 1 to 15 are associated with the letter B· 16 to 30 are associated with the letter I· 31 to 45 are associated with the letter N· 46 to 60 are associated with the letter G· 61 to 75 are associated with the letter OThe person managing the game (“the caller”) selects a number from the Bingo drum randomly, and then announces the letter and the number. The caller then sets aside that number so that it cannot be used again in that game. All the players then mark any squares on their card that match the letter and the number called. Once any player has five squares in a row, they announce “BINGO!” and claim their prize.For this program however, please note that:1. The player can announce “BINGO” as soon as (s)he gets one number for each letter, not necessarily in a row. For example, 2 25 31 58 70 would be a winning combination.2. Multiple winners are possible.The following picture shows a sample bingo card:public class BingoChip
{
private char letter;
