Answer:
1,712,304 ways
Step-by-step explanation:
This problem bothers on combination
Since we are to select 5 subjects from a pool of 48 subjects, the number of ways this can be done is expressed as;
48C5 = 48!/(48-5)!5!
48C5 = 48!/43!5!
48C5 = 48×47×46×45×44×43!/43!5!
48C5 = 48×47×46×45×44/5!
48C5 = 205,476,480/120
48C5 = 1,712,304
Hence this can be done in 1,712,304ways

Step-by-step explanation:
The 5 houses in both Oakcrest and 1980s category should not be counted twice. The correct probability is 105/220.
19% of the voters were in Favor of building the shopping center.
<u>Step-by-step explanation</u>:
- Number of votes in favor of the shopping center = 4,000
- Number of votes against the shopping center = 17,000
Total voters in the city = number of votes in favor of the shopping center + number of votes against the shopping center.
- Total voters = 4000 + 17,000 = 21,000.
Percentage= (No. of votes in favor of shopping center / total voters)
100
⇒ (4000/21,000)
100
⇒ (4/21)
100
⇒ 19%
∴ 19% of the voters were in Favor of building the shopping center.
