Respuesta :

Answer:

Probability of drawing a black card =  [tex]\frac{3}{10}[/tex] or 0.3 .

Step-by-step explanation:

Given : You draw a card at random from a deck that contains 3 black cards and 7 red cards.

To find : What is the probability of drawing a black card.

Solution : We have given that

Deck that contains  black cards  = 3.

Red cards = 7.

Total card = 10.

Probability of drawing a black card = [tex]\frac{3}{10}[/tex].

Probability of drawing a black card = 0.3.

Therefore,  Probability of drawing a black card =  [tex]\frac{3}{10}[/tex] or 0.3 .

Answer:

Probability of drawing a black card =   or 0.3 .

Step-by-step explanation:

Given: You draw a card at random from a deck that contains 3 black cards and 7 red cards.

To find: What is the probability of drawing a black card.

Solution: We have given that

A deck that contains  black cards  = 3.

Red cards = 7.

Total card = 10.

Probability of drawing a black card = .

Probability of drawing a black card = 0.3.

Therefore,  Probability of drawing a black card =   or 0.3 .
