Can anyone explain this to me? P(Jack is late to school any day) = 0.4 What is the probability that Jack will be late 2 days running?

So, say L = late
The probability of Jack being late (P(L)) = 0.4
So the probability of Jack being late twice in a row is P(L∩L) = 0.4 x 0.4 (because according to the question you've written the event of being late does not change on consecutive days)
So the answer is 0.16.
Hope this has helped
