For each day of the 5-day working week Tom can choose any
one of 6 newspapers to read at the lunchtime.
(i) How many different choices are possible in a week?
(ii) If Tom wants to read a different title each day, then how

1) The probability of both/all events occurring is determined by multiplying the probabilities of the individual events.
(1/6)^5 = ? (This is with replacement.)(Use the denominator)
