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?
