Just look at the percentages and make them into fractions. You can think about it like money. 50 cents is half of a dollar, so %50 is 1/2. for the decimals, you just take the percent and put a decimal point in front of the answer, so 28% is .28, 50% is .50, 18% is .18. For fraction to decimals, you could just put 1 divided by 4 into a calculator and it will tell you .25, which is the decimal, and 25 cents is one fourth of a dollar, so it works out.
Hope this helps! Let me know if you have any more questions!

Answer:
0.216
Step-by-step explanation:
If the probability of green, P(green) is 40%, the probability of red, P(red) is 60%.
The probability of a light being red is not affected by the colour of the previous light, so at each of the 3 lights, the probability of red is always 60%.
To find the probability that all three lights will be red, multiply the three probabilities together. (Convert them to decimals first).
0.6 x 0.6 x 0.6 = 0.216
Answer: $100,000
Step-by-step explanation:
Let P be the amount he invested in 5% profit .
then 250,000-P be the amount he invested in 10% profit .
The total profit he earns at 5% =5% of P
⇒The total profit he earns at 5 %=0.05P
Now, The total profit he earns at 10% =10% of (250,000-P)
⇒The total profit he earns at 10%=
According to the question,

Thus, the money he invest in the company that made 5%= $100,000
