<image>During the "International Day Against Drug Abuse," a city aired a public service announcement titled "Cherish Life, Stay Away from Drugs" for several consecutive days, aiming to make more citizens aware of the harmful effects of drugs. To understand the impact of this advertisement, anti-drug volunteers randomly selected 100 citizens aged within the intervals [10,20), [20,30), [30,40), [40,50), and [50,60) for a questionnaire survey. The sample frequency distribution histogram obtained is shown in the figure.
(1) Using stratified sampling by age groups from people aged 40 years and older, five people were randomly selected. Determine the number of people to be selected from the [50,60) age group.
(2) From the five people selected in (1), two will be randomly chosen as winners of this event. Calculate the probability that exactly one of the winners is from the [50,60) age group.
