Answer:
When a coin is tossed 6 times we have 26 = 64
outcomes which consist of
(i)
6 heads and 0 tail
(ii)
5 heads and 1 tail
(iii)
4 heads and 2 tail
(iv) 3 heads and 3 tail
(v) 2 heads and 4 tail
(vi) 1 heads and 5 tail
(vii) 0 heads and 6 tail
Given that X represent the difference between the
number of heads and tails.
(i) X
= 6 ? 0 = 6
(ii) X
= 5 ? 1 = 4
(i) X
= 4 ? 2 = 2
(i) X
= 3 ? 3 = 0
(i) X
= 4 ? 2 = 2
(i) X
= 5 ? 1 = 4
(i) X
= 6 ? 0 = 4
(i) X
= 6 ? 0 = 6
X
= 6, 4, 2, 0.
