#2. (20 (a) How many sample points in the experiment of tossing a coin 10 times? (b) How many combinations of 8 people are there taken 4 at a time? (c)Use Pascal\'s Triangle to redo (b) above would you expect? td) Adata set consists of household incomes. What kind of skewness
Solution
a)When 10 coins are tossed sample points = 210=1024
b) 8C4 ways = 2520
c) Pascal triangle

Hence 8C4 = 2520
d) Right skewed
