Question

What is the probability of getting all heads when 4 coins are tossed?

(a) \(\frac{1}{2}\)

(b) \(\frac{1}{4}\)

(c) \(\frac{1}{8}\)

(d) \(\frac{1}{16}\)

I got this question during an interview.

This intriguing question originated from Data Handling in chapter Data Handling of Mathematics – Class 8

Answer 1

Right choice is (d) \(\frac{1}{16}\)

To explain: A coin has two sides i.e. head and tail. When a coin is tossed, we can get either head or tail. There are 16 possibilities when 4 coins are tossed. The probability of getting all heads is \(\frac{1}{16}\).
