Can you solve and show your steps so I can see how to solve these types of questions?

There are 52 cards in a deck. There are 4 eights and 4 nines. What is the probability that if you cut the deck, you'll get an eight or a nine? Express your answer as a decimal number rounded to the hundredths place.

jim_thompson5910 · Answer

there are 4+4 = 8 cards that are either 8 or 9

jim_thompson5910 · Answer

this is out of 52 cards total

anonymous · Answer

reqd. p$$reqd. probability=\frac{ 4 }{ 52 }+\frac{ 4 }{52 }$$

jim_thompson5910 · Answer

so the probability as a fraction is 

8/52 = 2/13

use a calculator to get 2/13 = 0.15384615 and this rounds to 0.15, which is your final answer

$$P \left( A \cup B \right)=P \left( A \right)+P \left( B \right)$$
$$P \left( A \right)=\frac{ 4 }{ 52 }$$
Similarly P(B)
