Question

Suppose you toss a coin four times. What is the probability that you get heads on the second, third, and fourth tosses?

1. 12.5%
2. 0.1%
3. 25%
4. 0.5%​

Answer 1

Total possible outcomes  = (2)⁴ = 16  

Probability of getting all tail   = 1/16  

Probability of getting all heads   = 1/16

Probability = 1/16 + 1/16 = 2/16 = 0.125 = 12.5%
