Answer:

0.73

Step-by-step explanation:

Number of cards in a standard deck = 52

Number of black cards = 26

Number of face cards = 12

Probability of drawing either a black or face card

Probability = required outcome / Total possible outcomes

P(drawing a black card or face card) = (number of black cards / total card) + (number of face cards / total cards)

= 26/52 + 12 /52

= 0.5 + 0.2307692

= 0.73

Please help! In the question you have to find whether the number is either rational or irrational.

Mnenie [13.5K]

Answer:

Square root of 30 is irrational because the answer is a non-terminating decimal.

4/7 is rational because it is a fraction.

21 divided by the square root of 4 is irrational because the result is a non-terminating decimal.

Pi is irrational because it's a non-terminating decimal.

-27 is rational because rational numbers can be positive or negative.

I hope this is correct! :-)
