ACT Practice Math Questions: Probability

There’s a good chance that the ACT Math exam will contain one or more questions that deal with probability. There’s also a good chance that the odds of your answering those questions correctly will improve if you tackle the following practice questions.

Practice questions

1. Sheila has 4 black socks and 2 navy socks in her laundry pile. If she randomly selects one sock from the pile, sets it aside, and then picks another sock from the pile, what is the chance that she will select the navy pair?

The next question is based on the following information.

The discard pile for a children’s card game contains 6 green cards, 8 yellow cards, 10 blue cards, and several red cards. There are no other cards in the discard pile. The probability of randomly choosing a yellow card from the pile is 1/4. Armando shuffles the discard pile and places the whole pile face down in front of the players to ready it for further play.

2. To put a card into play, the players flip over the top card of the newly shuffled discard pile. What is the probability that the first player will flip over a green card?
