Coin probability = 1/2
Dice probability = 5/6
(1/2)x(5/6) = 5/12
If you have any more questions let me know!
The Z-value for a 90 percent confidence is 1.645
To find the sample size use the formula:
Sample size = Z-value x SD / error)^2
Using the provided information:
SD = 4,000 miles
Error = 500 miles
Sample size = ((1.645) (4000)/ 500)^2 = 173.18 = 174
Answer:
y=8
Step-by-step explanation:
SR=2×SG
AND SG=GR
3y-16=2×4
3y-16=8
3y=8+16
3y=24
y=8
Answer:
7
Step-by-step explanation:
Maybe just use a calculator instead lol
Answer:
a) Classical
b) Subjective
c) Empirical
Step-by-step explanation:
a) Classical probability: In classical probability, all the events have the same probability. When flipping a coin, the probability of getting tails is the same as the probability of getting tails, therefore, the probability of both events is 50%.
b) Subjective probability: Subjective probability is derived from a personal judgement based on previous experiences. In this case, John would be calculating his probability of receiving A's based on his previous semesters.
c) Empirical probability: is the ratio between the number of outcomes a scenario happens and the total of trials in an ACTUAL EXPERIMENT. In this case, the reporter would be calculating this probability based on his previous experiences attending actual conferences.
