The number of severe storms that strike city J in a year follows a binomial distribution with [math]n = 5 [/math] and [math]p = 0.6 [/math]. Given that [math]m[/math] severe storms strike city J in a year, the number of severe storms that strike city K in the same year is [math]m[/math] with probability 1/2, [math]m+1[/math] with probability 1/3, and [math]m+2[/math] with probability 1/6.
Calculate the expected number of severe storms that strike city J in a year during which 5 severe storms strike city K.
