### There are 11 players in team A. It is known that four of them (call them high scoring) score a penalty with probability 0.8 each and the other seven (low-scoring) with probability 0.5 each. There is a penalty shoot-out with another team, team B (of 11 players), in which every player from each team takes exactly one shot, so that 22 shots are to be taken. Every player in team B scores with probability 0.64. The team that scores the most goals wins. Which team is expected to win? Justify your answer

The majority of college-level probability practice problems will include questions related to statistics with the answers and explanations that will explain how a certain riddle has been addressed. Just think about flipping a coin or throwing dice as an example or finding a red marble in the bag with the green marbles. It is all about probability where the college probability will have more complex questions with the necessity of different equations and quantitative data questions where formulas must be used to determine the possibility of a certain outcome or prognosis. We offer help by letting you see various probability examples.
