Question

Julia enjoys shooting paper balls into the wastebasket across her office. She misses the first shot 50% of the time. When she misses on the first shot, she misses the second shot 20% of the time. What is the probability of missing two shots in a row

Answer 1

You can do 1/5 times 1/2 to get the result of 1/10 or 10%

Answer 2

`\bf\textbf{Probability that Julia misses two shots in a row = }(1)/(10)`

Explanation:

Julia enjoys shooting paper balls into the wastebasket across her office.

She misses the first shot 50% of the time.

`\text{Probability that Julia misses the first shot = }(1)/(2)`

When she misses on the first shot, she misses the second shot 20% of the time.

`\text{Probability that Julia misses the second shot = }(1)/(5)`

Now, we need to find the probability of missing two shots in a row

`\text{Probability that Julia misses two shots in a row = }(1)/(2)* (1)/(5)`

`\bf\textbf{Probability that Julia misses two shots in a row = }(1)/(10)`
