Question

What is the probability of getting 2 tails and 1 head when 3 coins are tossed?

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

(b) \(\frac{1}{13}\)

(c) \(\frac{3}{8}\)

(d) \(\frac{1}{3}\)

I got this question during an interview for a job.

Asked question is from Data Handling topic in chapter Data Handling of Mathematics – Class 8

Answer 1

Right option is (c) \(\frac{3}{8}\)

To elaborate: A coin has two sides i.e. head and tail. When a coin is tossed, we can get either head or tail.

The possible outcome when 3 coins are tossed are HHH, HHT, HTH, HTT, THH, THT, TTH, TTT. The probability of getting 2 tails and 1 head is \(\frac{3}{8}\)
