While hiking on San Miguel Island, it is possible to see six different species of pinniped (California sea lions, northern fur sealsnorthern elephant seals, harbor seals, and less frequently, Guadalupe fur seals and sea lions)but we will concern ourselves with only two species: Callorhinus ursinus (the northern fur sealand Zalophus californianus (the California sea lion) While on San Miguel there is a 64% chance of seeing a California sea lion while there is only 25% chance of seeing a northern fur seal . There is a 16% chance of both a California sea lion and a northern fur seal . What is the probability of seeing a least one of these creatures ?

Are seeing a northern fur seal and seeing a California sea lion while on San Miguel Island independent events? Please explain.
