The probability of choosing a card with the number 4 is 1/10.

The probability of choosing a card that has a digit 1 on it is 1/5.

The probability of choosing a card that does not have a digit 1 on it is 4/5.

What are the probabilities?

Probability determines the chances that a random event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.

The probability of choosing a card with the number 4 = cards with the number 4 / total number of cards = 1/10

The probability of choosing a card that has a digit 1 on it = cards with the number 1 / total number of cards = 2/10 = 1/5

The probability of choosing a card that does not have a digit 1 on it = cards that do not have the number 1 / total number of cards = 8/10 = 4/5
