Question

read the story.
next week, wendy is going on a 4 - day ski trip to mount flurry. she wants to ski on fresh powder, so she checks the weather forecast. each day has a 60% chance of snow. how likely is it to snow on all 4 days?
wendy simulates the situation by creating a deck of 20 cards, each labeled with a different number from 1 to 20. she picks a card, then returns it to the deck, 4 times. each time a number greater than 8 appears, it represents a snowy day.
this table shows the results of 100 trials:
based on wendys results, what is the probability that it will snow on all 4 days?
%

Explanation:

Step1: Recall the formula for experimental probability

Experimental probability \(P=\frac{\text{Number of favorable outcomes}}{\text{Total number of trials}}\)

Step2: Identify the number of favorable outcomes and total number of trials

The number of favorable outcomes (number of times a number greater than 8 appears 4 times) is 13. The total number of trials is 100.

Step3: Calculate the probability

\(P = \frac{13}{100}=0.13\)

Answer:

13
