Erik is investigating whether the number of goals scored by a football team in a game can be modelled using a binomial distribution. He uses the random variable X X\,X to denote the number of goals scored in a game and believes X∼B(4,0.20)X \sim B(4, 0.20)X∼B(4,0.20)
Using Erik's model, find P(X≥3)P(X \geq 3)P(X≥3)
