The number of severe accidents that occur in Riyadh in a year follows a Binomial distribution with a chance of 60% of every 5 accidents to be severe. Given that m severe accidents happen in Riyadh, the number of severe accidents that occur in Jeddah in the same year is m with probability 50%, m + 1 with probability of 33.33%, and m + 2 with probability 16.67%. Calculate the expected number of severe accidents that happen in Riyadh in a year during which 5 severe accidents occur in Jeddah (Hint: it is a conditional expectation problem)
