What is the probability of flipping a coin three times and getting at least two heads?

Answer explanation

The probability of getting at least two heads in three coin flips is calculated by finding the probability of getting exactly two heads and the probability of getting three heads, then adding them together. This results in 3/8.

What is the probability of drawing a red card from a standard deck of 52 playing cards?

Answer explanation

To calculate the probability of drawing a red card, we note that half of the deck consists of red cards (26 out of 52), so the probability is 1/2.
