The letter tiles W, I, S, D, O, M are placed on a box. Without looking, Abby picks a letter tile from the box. What is the probability that the letter she picks is a vowel? Write your answer in the simplest form of a fraction.
There are two vowels in the set of tiles: I and O. Abby has a total of 6 tiles to choose from. Therefore, the probability of her choosing a vowel is:
2/6 = 1/3
So the answer is a fraction 1/3.
Mr. Lim has a bag with some marbles colored red, yellow, green, blue, and white. The marbles are identical in number. If there are 40 marbles in the bag, how many marbles of each color are in the bag?
If there are five colors of marbles and the marbles are identical in number, Mr. Lim has 40/5= <<40/5=8>>8 marbles of each color in the bag. Therefore, there are 8 red marbles, 8 yellow marbles, 8 green marbles, 8 blue marbles, and 8 white marbles in the bag.
Mr. Lim has a bag with some marbles colored red, yellow, green, blue, and white. The marbles are identical in number. Mr. Lim will conduct a chance experiment by randomly drawing a marble from the bag and then returning it after noting the color. Based on 50 trials, how many green marbles will Mr. Lim expect to pick?
If the marbles are identical in number, then the probability of picking a green marble in a single trial is 1/5, or 0.2. We can use this probability to determine the expected number of green marbles in 50 trials:
Expected value = Probability of success x Number of trials
Expected value = 0.2 x 50 = 10
Therefore, Mr. Lim can expect to pick 10 green marbles in 50 trials.

Out of the letters in the sample space, the consonants are b, c, d, and f. There are a total of 6 letters, so the probability of picking a consonant is:
4/6 = 2/3
So the answer is a fraction 2/3.
Therefore, the correct response is:
Start Fraction 2 over 3 End Fraction.

Out of the letters in the word MODELS, the vowels are O and E. The probability of selecting each of these letters is 16/96 (since there are 96 total equally likely outcomes). Therefore, the probability of selecting a vowel letter from the word MODELS is:
(16/96) + (16/96) = 32/96 = 1/3
So the answer is a fraction 1/3.
Therefore, the correct response is:
Start Fraction 1 over 3 End Fraction.
A deck of 10 cards labeled 1–10 is shuffled. One card is selected at random. If the experiment is repeated 120 times, how many times will you expect to select number 5?(1 point)
