Answer 1

Answer:

(i) p(not E) = 1 -P(E)

= 1 - 0.2

= 0.8

(ii) True

(iii) 1

(iv) 19/40

Answer 2

(i) P(E) = 0.2, P(Ē) = 1 - P(E) = 1 - 0.2 = 0.8

(ii) True. For any event probability lies between 0 and 1.

(iii) For sure/certain event probability is 1. Similarly for impossible Event probability is 0.

(iv) Probability =

$\frac{number \: of \: favourable \: outcomes}{total \: number \: of \: possible \: outcomes}$

Therefore, Probability for heads =

$\frac{19}{40}$

= 0.475
