    λ =   sum of (0*12 + 12*1+ 4*2 + 1*3 + 1*4)/30

    λ =  (12 + 8 + 3+4)/30 =  27/30 = 0.9  goals per game

    (a)  What is the probability that they will score 

    2*0.9 or 1.8 goals in less than 3 unit time 

     

    I don't really understand what they are asking 

    3 unit time , 3 games?

    so are they asking in  0,1, or 2 games 

    or do the count  

    if part of the 3 games if i 

    2 games and 1/2 of third game 

    so I could determine , using the 

    probability of scoring   

    0, 1, or 2 goals in 2 games  

    You can't check exactly 1.8 goals.  

    I'm not really sure what they want?

    In that case I probably can't either.
