What is the probability of getting exactly 5 “heads” in 10 coin flips?
Which expression represents the probability of rolling a 5 exactly three times in ten rolls of a number cube with six sides?
A number cube with six sides is rolled seven times. The probability of getting a 4 exactly twice is ⇒ 0.234.
7C2(1/6)^2(5/6)^5
Using the information on the left, combine the individual probabilities to compute the probability that Peter will pass the quiz.
The distribution is
roll a six-sided number cube 10 times. P = ⇒ 0.246 roll a six-sided number cube 20 times. P =
Which of the following ideas did you include in your response? Check all of the boxes that apply.
p represents the number of trials✔ probability of successnumber of successesprobability of failure.
Explain why the second result is less.
As the number of trials increases, the probability of getting exactly a specific number of successes that is far from the new mean decreases. For 10 trials with a 50% success rate, 5 is the expected value (mean) and has the highest probability. However, for 20 trials, the expected value is 10, and getting exactly 5 successes is much less likely because the distribution has spread out and centered around a higher value.
