Answer:
The probability of picking a red card is 50% chance.
The probability of drawing a (2) card is 1 in 13 chance.
The probability of drawing a red card or a two is a 30/52 probability.
Explanation:
To find the probability of picking a red card, we must look at how many red cards there are in a standard deck of 52 cards. There are exactly 26 red cards out of total 52 cards, which is exactly half. Therefore, the probability is 50%, 1/2 chance, or 26/52 chance, however you prefer to write it.
To find the probability of picking a card that is a two, we must look at how many two cards there are in a standard deck. There are exactly 4 cards with the number two on them, meaning the probability is 4 out of 52, or 1 out of 13.
To find the probability of picking a card that is a red card OR a two, we must look at the probabilities of picking those cards individually. Red card has a 26 out of 52 chance, and two card has a 4 out of 52 chance.
**When doing problems about probability, the type of vocabulary used in the question is very important. (AND) means that you have to multiply the two values by each other. (OR) means that you have to add the two values together.**
Because the word (OR) was used in the last question, this means that we need to add 26/52 and 4/52 together.
This makes our probability a 30 out of 52 chance of picking a red card or a two.
