Simulating the probability of A and B

You can also use simulation to estimate the probability of two events both happening.

This exercise is part of the course

Foundations of Probability in R

Exercise instructions

Randomly simulate 100,000 flips of coin A, each of which has a 40% chance of being heads. Save this as a variable A.
Randomly simulate 100,000 flips of coin B, each of which has a 20% chance of being heads. Save this as a variable B.
Use the "and" operator (&) to combine the variables A and B to estimate the probability that both A and B are heads.

Hands-on interactive exercise

Have a go at this exercise by completing this sample code.

# Simulate 100,000 flips of a coin with a 40% chance of heads
A <- 

# Simulate 100,000 flips of a coin with a 20% chance of heads
B <- 

# Estimate the probability both A and B are heads
