Alife scientist worksheet has the names of 36 animals of these 18 fed on seeds 15 feed on insects and 6 feed on both seed and insects a student randomly selects one animal for a study what is the probability that the chosen animal feeds on seeds or insects or both

The  probability that the chosen animal feeds on seeds or insects or both is:

Let A denote the event that the animal feed on seeds.

B denote the event that the animal feed on insects

and A∩B denote the event that the animal feed on both seed and insects.

and A∪B denote the event that the animal feeds on seeds or insects or both.

Let P denote the probability of an event.

Now, based on the information from the question we have:

Now, we know that:

Hence, on putting the values we have:
