Answer : 300
30% of 1000 is 300
To get from percentage move the decimal over to the left by 2 and multiply by total money:
1,000,278 x 0.1290 = 129036. This is how much he took out.
How much he has left is just the initial amount minus this
1,000,278-129036 = 871242
Answer:
- 60.8%
- 39.2%
Step-by-step explanation:
It is convenient to put the numbers into a table and fill in the remaining values. In the attachment, the given numbers are blue. The black numbers are the values that make the totals add up.
__
1. The probability of interest is the sum of the numbers in the table spaces shaded blue. You can find that sum several ways. The usual way used for an "OR" probability is ...
p(<16 or night) = p(<16) + p(night) - p(<16 & night)
= 37.1% + 27.5% - 3.8%
= 60.8%
__
2. This probability is the complement of the one in the first part. It is the value in the yellow-shaded box.
p(≥16 & day) = 1 - p(<16 or night) = 1 -60.8% = 39.2%
