Question

John has three chances of throwing and hitting the target to win the prize. One hit wins john the prize. What is the probability of john not winning if any given has a 90% chance of hitting target

Answer 1

If John has a 90% chance of hitting the target on each throw, then the probability of not hitting the target on any given throw is 10% or 0.10.

Since John has three chances to hit the target, the probability of not hitting the target on all three throws is calculated by multiplying the individual probabilities together:

0.10 * 0.10 * 0.10 = 0.001

Therefore, the probability of John not winning the prize is 0.1% or 0.001.
