The answer in the last one
Answer:
1/8
Step-by-step explanation:
When three fair coins are tossed there is a chance of occuring eight combinations. Hence the probability is 1/8. Each outcome of each flip of a fair coin has a probability of 0.5.
Answer:
30x25/100
25%=7,5$
30+7,5$=37,5$
The original price was 37,5 because you had to first find out what was 25% in $ to then do the opposite of a sale since we are finding the original price so we have to add it to 30$ since 30$ was the price after the sale.
Hope this helps, have a good day!
