When selecting one card from a pile of 10 cards, the probability of choosing the number 4 is 1/10.
If the experiment is repeated 240 times, the expected number of times the number 4 would be selected is:
(1/10) * 240 = 24 times
Therefore, you would expect to select the number 4 24 times out of 240 selections.
The correct answer is 24 times.
20%
Explanation:
- There are a total of 10 letters in the word CONNECTION.
- There are 2 letter N's in the word.
- The probability of drawing a card with the letter N on it is 2/10 = 1/5 = 20%.
- Therefore, the probability of drawing a card with the letter N on it is 20%.

There are a total of 20 flips, and 5 of them result in heads.
The experimental probability of getting heads is:
Number of heads / Total flips = 5 / 20 = 1/4 = 25%
Therefore, the experimental probability of getting heads is 25%.

There are a total of 16 rolls, and the number 4 comes up 2 times.
The experimental probability of rolling a 4 is:
Number of 4s rolled / Total rolls = 2 / 16 = 1/8
Therefore, the experimental probability of rolling a 4 is 1/8.
