you randomly select one card from a 52-card deck. find the probability of selecting a red jack or a red eight
p(red jack or red eight) = p(red jack) + p(red eight)
p(red jack or red eight) = 2/52 + 2/52
p(red jack or red eight) = 4/52
p(red jack or red eight) = 1/13
The probability of selecting a red jack or a red eight is 1/13.
By use of observations and some patterns, you can figure out the probability, or likelihood, of getting a certain card, so when you're pretty sure, you can bet lots of money.
there are 4 aces therefore the probability is 4/52=1/13 there are 4 8's therefore the probability would be the same 1/13 :
if aces and 8's together it would be 8/52=2/13
You randomly select one card from a deck of 52 cards. Find the probabilty of selecting an ace or a 8? -------------------------- # of ways to succeed: 8 # of possible outcomes: 52 P(ace or 8) = 8/52 = 2/13 = 0.153846... Cheers,
