Simulating probability of A or B
In the last multiple choice exercise you found that there was a 64% chance that either coin A (60% chance) or coin B (10% chance) would come up heads. Now you'll confirm that answer using simulation.

Exercise instructions
- Use
rbinom()to simulate 100,000 flips of coin A, each having a 60% chance of being heads. - Use
rbinom()to simulate 100,000 flips of coin B, each having a 10% chance of being heads. - Use these to estimate the probability that A or B is heads.
