In a group of people, some are in favor of genetic engineering and others are against it.

Two persons are selected at random from this group and asked whether they are in favor

Venn diagram and a tree diagram for this experiment. List all the outcomes included in

each of the following events and mention whether they are simple or compound events.

(a)

Both persons are in favor of genetic engineering.

(b)

At most one person is against genetic engineering.

(c)

Exactly one person is in favor of genetic engineering
