Alternative solution/shortcut:

All 10 members have equal opportunity to be chosen for one position. So, the probability that Harry will be either member chosen to be the secretary (1/10) or the member chosen to be the treasurer (1/10) is 1/10+1/10 = 1/5

Sorry, I can't post question as it is part of the index page somebody can use with OG12. Otherwise it would be copyright violation.
