A basket contains 6 pumpkins and 4 onions. What is the probability of selecting at random one onion?

The total number of items in the basket is 6 + 4 = 10.

The probability of selecting an onion at random is the number of onions divided by the total number of items:

4 onions / 10 total items = 0.4

Therefore, the probability of selecting at random one onion is 0.4 or 40%.

There are a total of 6 + 4 = 10 items in the basket.

There are 4 onions in the basket.

So, the probability of selecting at random one onion is 4/10 = 2/5 = 0.4.
