Which ratio best defines theoretical probability?
2 answers:
Answer: Second option is correct.
Step-by-step explanation:
Since we know that Theoretical probability is the ratio of the number of favorable outcomes to the number of possible outcomes.
It means the possibility of favorable outcome out of all possible outcomes.
Mathematically, it is expressed as :
Hence, Second option is correct.

Answer:
a. 0.71
b. 0.9863
Step-by-step explanation:
a. From the histogram, the relative frequency of houses with a value less than 500,000 is 0.34 and 0.37
-#The probability can therefore be calculated as:
Hence, the probability of the house value being less than 500,000 is o.71
b.
-From the info provided, we calculate the mean=403 and the standard deviation is 278 The probability that the mean value of a sample of n=40 is less than 500000 can be calculated as below:
Hence, the probability that the mean value of 40 randomly selected houses is less than 500,000 is 0.9863
