The probability of picking a consonant is 4/6, which simplifies to 2/3.
So the answer is 2/3.

In the word MODELS, there are 2 vowels (O and E) out of a total of 6 letters. The probability of selecting a vowel letter is therefore 2/6, which simplifies to 1/3.
So, the answer is:

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)

Since there is only 1 card labeled as 5 out of 10 total cards, the probability of selecting number 5 is 1/10.
If the experiment is repeated 120 times, you would expect to select number 5 approximately 1/10 * 120 = 12 times.
So, the answer is 12.

The letter A is not one of the letter tiles provided (H, O, N, E, S, T), so the probability of selecting letter A is 0.
Therefore, the answer is 0.
