A coin is tossed 200 times and head appeared 120 times. The probability of getting a head in this experiment is
(a) 2/5
(b) 3/5
(c) 1/5
(d) 4/5

Solution:

Given a coin is tossed 200 times

We know that a fair coin has only 2 outcomes but only one outcome at a time

Hence, total sample space is 200

Given that head appeared 120 times

The probability of getting head in the experiment is the ratio of favourable outcomes to total outcomes

Probability = 120/200 = 3/5

✦ Try This: A coin is tossed 10 times and head appeared 2 times. The probability of getting a head in this experiment is (a) 2/5, (b) 3/5, (c) 1/5, (d) 4/5

Given a coin is tossed 10 times

We know that a fair coin has only 2 outcomes but only 1 at a time

Hence, total sample space is 10

Given that head appeared 2 times

The probability of getting head in the experiment is the ratio of favourable outcomes to total outcomes

Probability = 2/10 = 1/5
