Final answer:
The probability that Product 1 will last for more than a year is 950/1,000 as a fraction, 0.95 as a decimal, and 95% as a percent.
Step-by-step explanation:
The question asks for the probability that Product 1 will last for more than a year. To calculate this, you divide the number of test items that lasted more than a year by the total number of test items. In this case, 950 out of 1,000 test items lasted more than a year.
To express this probability as a fraction, decimal, and percent, we follow these steps:
- Write the probability as a fraction: ½ 950/1,000.
- Convert the fraction to a decimal by dividing the numerator by the denominator: 950 ÷ 1,000 = 0.95.
- Finally, convert the decimal to a percent by multiplying by 100: 0.95 × 100 = 95%.
Therefore, the probability that Product 1 will last for more than a year is 950/1,000 as a fraction, 0.95 as a decimal, and 95% as a percent.
