Question

A weighted coin has a 0.599 probability of landing on heads. What is the probability that it takes 5 flips for the first head to occur?

Answer 1

0.411^5 times 0.599

Explanation:

0.599 chance of landing on heads.

0.411 chance of not landing on heads.

0.411 times 0.411 times 0.411 times 0.411 times 0.411 (for the 5 flips that do not land on heads) times 0.599 (for the time that it does land on heads).
