Question

the following set of chips is placed inside a bag. then, without looking, a chip is pulled out of the bag. what is the probability that the chip chosen will contain a filled - in square? submit your answer as a simplified fraction, as well as a decimal and percentage, both rounded to the hundredths place.

Explanation:

Step1: Determine total number of chips

There are 5 chips in total.

Step2: Determine number of favorable outcomes

There is 1 chip with a filled - in square.

Step3: Calculate probability as a fraction

The probability $P$ as a fraction is $\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}=\frac{1}{5}$.

Step4: Calculate probability as a decimal

$\frac{1}{5}= 0.20$ (already rounded to hundredths place).

Step5: Calculate probability as a percentage

$0.20\times100 = 20.00\%$ (already rounded to hundredths place).

Answer:

Fraction: $\frac{1}{5}$
Decimal: $0.20$
Percent: $20.00\%$
