Sagot :

The question says you draw a card at random from a deck that contains 3 black cards and 7 red cards.

What is the probability of drawing a black card?

Recall,

Probability = Number of possible outcome

Number of favorable outcome

There are 3 favorable outcomes (the 3 black cards)

There are 10 possible outcomes ( the 3 + 7 = 10 cards)

Therefore,

P(draw a black card) = 3/10

P(draw a black card) = 0.30 (to 2 decimal places)
