Answer:
The experimental probability of throwing a five is 0.087.
Step-by-step explanation:
Given:
Number of trials (n) = 100
Number of times 5 appears (x) = 14
Let the event of occurrence of 5 be success and the probability represented by 'p'. So, all the other numbers occurrence is failure and its probability is represented as 'q'.
Probability of success is given as:
Favorable event is occurrence of 5. So, its number is 1 as there is only one 5 in the die. Total outcomes are 6 as there are six numbers. So,
Now, probability of failure is given by the formula:
Now in order to find the experimental probability of 14 successes out of 100 trials, we apply Bernoulli's theorem which is given as:
Plug in all the given values and find the probability of 14 successes. This gives,
Therefore, the experimental probability of throwing a five is 0.087.
Answer:
Step-by-step explanation:
A fraction can be found be taking the current amount over the total amount:
Since Darlene has only typed 23 pages out of 59, her fraction is 23 over 59. Fractions must always be in simplest form, which means that both the numerator and denominator can no longer be divided by the same factor. Since the numbers 23 and 59 are both prime and have no other factors other than 1 and themselves, the fraction 23/59 is in simplest form.
