Let

X

be the set of all five digit numbers formed using 1,2,2,2,4,4,0. For example, 22240 is in

X

while 02244 and 44422 are not in

X

. Suppose that each element of

X

has an equal chance of being chosen. Let

p

be the conditional probability that an element chosen at random is a multiple of 20 given that it is a multiple of 5 . Then the value of

38 p

is equal to :
