We know that there are 10 articles of clothing (5 shirts and 5 pairs of shorts). First, you need to determine how many of these shirts and shorts are either blue or black. The problem says Malcolm has one black shirt, one blue shirt, two blue pairs of shorts, and one black pair of shorts.

This means he has a 5 in 10 chance of picking clothing that is blue or black.

To find the probability of an event, we will use the following formula:

So, given the event of drawing a 3, we can calculate the following:

\text{number of ways event can happen} = 4

Because there are 4 ways we can draw a 3 from the deck:

• 3 of clubs
• 3 of spades
• 3 of diamonds
• 3 of hearts

Now, we can calculate the following:

\text{total number of possible outcomes} = 52

Because there are 52 cards we could potentially draw from a deck of cards.

Knowing this, we can substitute into the formula. We get

Therefore, the probability of drawing a 3 from a deck of cards is .

To find the probability of picking a purple shirt from the pile of shirts on Joey's bed, we need to set up a fraction like this:

The problem tells us that Joey has 3 purple shirts, so we can put that in the numerator. We are also told that the total number of shirts on Joey's bed is 10, so 10 goes on the bottom of the fraction. Therefore, Joey has a chance of picking a purple shirt.

The probability is expressed as the circumstance out of the whole number available.

The number of marbles that are red is 7, and the whole number of marbles is 20.

Therefore the probability is
