Question

a game has 9 red cards 4blue cards and 7 gold cards a card is picked at random what is the probability that the card picked is a blue card

Answer 1

Probability = required outcome / all possible outcome

required outcome = 4

substitute into the formula

`\text{probability}=(4)/(20)=(1)/(5)`
