Question

A Coin is tossed 200 times. We Obtain a head 20 times.on tossing the coin at random, Find the Probability of getting (¡)a head (¡¡) a tail​

Answer 1

Answer:

(i) 1/10 or 0.1  (ii) 9/10 or 0.9

Step-by-step explanation:

Total Events = 200

Head = 20 times

Tail = 200 -20 = 180 times

The Formula for calculating Probability is

(number of positive outcomes)/(number of total events)

(i) 20/200 = 1/10 or 0.1

(ii) 180/200 = 9/10 or 0.9
