Question

We surveyed children to see if they liked to eat apples. We looked at two groups of children: ages 3-7 and ages 8-12. For a random selection, the probability of 3-7 year old or a 8-12 year old liking apples or not is given in the following table:

One of these children is selected at random.

a.) Find the probability the child likes apples.

b.) Find the probability the child is between the ages of 8-12.

c.) Find the probability the child is aged 8-12 and likes apples or is aged 3-7 and likes apples.

Likes Apple Does Not Like Apples Ages 3-7 0.25 0.31 Ages 8-12 0.30 0.14

Explanation / Answer

a)the probability the child likes apples=0.25+0.30=0.55

b)the probability the child is between the ages of 8-12=0.30+0.14=0.44

c)the probability the child is aged 8-12 and likes apples or is aged 3-7 and likes apples=0.30+0.25=0.55
