You toss a coin a randomly selecte a number from 0 to 9. What is the probability of getting tails and selecting a 9?
In-s [12.5K]
First lets find the probability of landing tails. Because there is 1 way to get tails and 2 possible outcomes, the probability is 1/2.

Now, lets find the probability of selecting a 9. Since this includes 0, there are 10 possible outcomes and 1 way to get a 9, so the probability is 1/10.

To find them combined, multiply:

1/2 * 1/10
1/20
0.05

Hope this helps!
