Hilda and 7 friends attended all four games of T20
[ad_1]
Hilda and seven (7) friends (of course I was one of the friends) attended all four games
of T20 cricket games between Pakistan and the West Indies in 2017. As her
contribution, she had to purchase eight sandwiches for each of the games on the
morning of each match.
(a) The first game was held on Saturday 25th March 2017 in Barbados. She went to
the Massy (in Hastings) to get the sandwiches. The manager had informed her
that the store has two types of sandwiches, chicken and cheese (sandwiches are
not labeled). He said that past experience had shown that the probability of a
customer getting a cheese sandwich is independently 0.3. She selected eight
sandwiches at random and paid for them.
