the table shows the results of spinning a four-colored spinner 50 times. find the experimental probability and express it as a decimal.
It is not possible to answer this question without knowing the outcomes of the 50 spins and the colors on the spinner.
you roll a number cube 20 times. the number 4 is rolled 8 times. what is the experimental probability of rolling a 4?
The experimental probability of rolling a 4 is 8/20.
Simplifying this fraction gives a decimal value of 0.4 or 40%.
A. 40%
B. 25%
C. 20%
D. 17%
The correct answer is A. 40%.
the probability of winning a game is 15%. if you play 20 times, how many times should you expect to win?
A. 5 times
B. 3 times
C. 6 times
D. 15 times
To find the answer, we can use the formula:
Expected number of wins = Probability of winning x Number of times played
Expected number of wins = 0.15 x 20 = 3
Therefore, you should expect to win 3 times if you play the game 20 times.
The answer is B. 3 times.
the probability of having a winning raffle ticket is 20%. if I bought 50 tickets, how many winning tickets should you expect to have?
A. 3
B. 8
C. 10
To find the answer, we can use the formula:
Expected number of winning tickets = Probability of winning x Total number of tickets
Expected number of winning tickets = 0.20 x 50 = 10
Therefore, you should expect to have 10 winning tickets if you buy 50 raffle tickets.
The answer is C. 10.
A company finds 5 defective toys in a sample of 600. predict how many defective toys are in a shipment of 24,000.
