Question

Cory is a bird watcher. He estimates that 30% of birds he sees are american robins 20% are darkeyed juncos and 20% are song sparrows. What is the probability that he atleast one of the next five birds he sees is a darkeyed junco

Answer 1

Based on the number of times that a darkeyed junco was spotted in the simulation, the probability of seeing at least one darkeyed junco in the next five birds is 70%.

What is the probability of seeing the darkeyed junco?

Out of 20 simulations, the darkeyed junco was spotted 14 times (simulation results with 3 or 4).

This gives the probability of seeing at least one darkeyed junco as:

= 14 / 20 simulations

= 70%
