Randomly generate 100 pets from the choices dog, cat, hamster and goldfish with equal probability of each being chosen. Display the first six values in pets and store these in the object first. Count the number of each pet and store these in the object counts (Hint: you may need to convert petsto a factor first).

Because you will be generating a random sample, we set a seed for R’s random number generator, so your results will be the same as Dodona’s.
