Answer:
<u>The probability that Julia makes at least one successful throw is 90%</u>
Step-by-step explanation:
1. Let's review the information provided to us to help Julia to answer the question correctly:
Probability that Julia misses the first shot = 50%
Probability that Julia makes the first shot = 50%
When she misses on the first shot, she misses the second shot 20% of the time. Therefore after missing the first shot, she makes the second shot 80% of the time.
Probability that Julia misses both shots = 50% * 20% = 0.5 * 0.2 = 0.1 = 10%
2. What is the probability of making at least one successful throw?
Probability of making at least one successful throw = 1 - (Probability that Julia misses both shots)
Probability of making at least one successful throw = 100% - 10%
<u>The probability that Julia makes at least one successful throw is 90%</u>
Answer:
P=0.0899.
Step-by-step explanation:
We know that are 5 black balls and 9 red balls in an urn. If 4 balls are drawn without replacement. We calculate the probability that exactly 3 black balls are drawn.
Therefore, we have 14 balls in an urn.
We calculate the number of possible combinations:

We calculate the number of favorable combinations:

Therefore, the probability is:
P=90/1001
P=0.0899.
