Question

The probability of randomly drawing a red card from a bag that contains red, blue, and green cards is 3/10. What is the probability of not drawing a red card?

Answer 1

If the probability of drawing a red card is 3/10, then if we take this fom a whole, 10/10, we can find the probability of not choosing a red card.
10/10-3/10=7/10

The probability of not drawing a red card is 7/10 or 70%.
