The number of flipping a coin is 5
Total number of outcome= 32
(H,T) (H,T) (H,T) (H,T) (H,T)

= 0.125
Answer to the question 2
Number of letters = 6
3 letters string cab be constructed by using 3 letters = 63
= 216
Answer to the question 3
Given that
X= 1,2,3,4,5
P(X)= 1/5
P (X≤ 3 ¿= P (X=1) +P (X=2) + P (X=3)
= 1/5+1/5+1/5
= 3/5
= 0.6
