The P(draw a black card) is 3/10.

<u>Step-by-step explanation:</u>

It is given that the deck contains 3 black cards and 7 red cards.

Therefore, the total number of cards in the deck = 7 red + 3 black = 10 cards.

Now, we need to find the possible outcomes of getting a black card. So, the number of black cards in the deck = 3 black cards.

<u>The formula to find the probability is given by :</u>

Probability = Number of required event / Total number of outcomes.

Here, the required event is getting a black card out of 10 cards in the deck.

  • The number of required event is 3.
  • The total number of outcomes is 10.

Probability (to draw black card) = 3/10.

What does it mean to have a positive exponent?
Anit [1.1K]
Having a positive exponent means having a positive number as a power for a value or a variable.

For example:
x^{2}  
Here, the variable x has a positive exponent because it has a power of positive (+) 2

\frac{1}{ 2^{4} } 
This expression has a positive exponent because the number 1 has a power of positive (+)1 and the number 2 has a power of positive (+)4

x^{-2}
This is not a positive exponent because the variable x has a power of negative  (-)2
The positive exponent for x^{-2} is \frac{1}{ x^{2} }.

\frac{1}{ 2^{-4} }
This expression doesn't have a  positive exponent. Though number 1 in the numerator has a positive power (exponent), the number 2 in the denominator has a power of negative (-)4
The positive exponent for \frac{1}{ 2^{-4} } would be 2^{4}.

NOTE: The terms Power and Exponent have he same meanine i.e. They are the same !!!
